text: High entropy alloys (HEAs) are highly suitable candidate catalysts for oxygen
evolution and reduction reactions (OER/ORR) as they offer numerous parameters
for optimizing the electronic structure and catalytic sites. Herein, FeCoNiMoW
HEA nanoparticles are synthesized using a solution‐based low‐temperature approach.
Such FeCoNiMoW nanoparticles show high entropy properties, subtle lattice distortions,
and modulated electronic structure, leading to superior OER performance with an
overpotential of 233 mV at 10 mA cm−2 and 276 mV at 100 mA cm−2.
Density functional theory calculations reveal the electronic structures of the
FeCoNiMoW active sites with an optimized d‐band center position that enables suitable
adsorption of OOH* intermediates and reduces the Gibbs free energy barrier in
the OER process. Aqueous zinc–air batteries (ZABs) based on this HEA demonstrate
a high open circuit potential of 1.59 V, a peak power density of 116.9 mW cm−2,
a specific capacity of 857 mAh gZn−1,
and excellent stability for over 660 h of continuous charge–discharge cycles.
Flexible and solid ZABs are also assembled and tested, displaying excellent charge–discharge
performance at different bending angles. This work shows the significance of 4d/5d
metal‐modulated electronic structure and optimized adsorption ability to improve
the performance of OER/ORR, ZABs, and beyond.

text: Developing cost-effective and high-performance thermoelectric (TE) materials
to assemble efficient TE devices presents a multitude of challenges and opportunities.
Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant
elements. However, the challenge lies in its poor electrical conductivity. Herein,
an efficient and scalable solution-based approach is developed to synthesize high-quality
Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement
and annealing treatments, the dried powders are consolidated into dense pellets,
and their TE properties are investigated. Pb doping effectively increases the
charge carrier concentration, resulting in a significant increase in electrical
conductivity, while the Seebeck coefficients remain consistently high. The calculated
band structure shows that Pb doping induces band convergence, thereby increasing
the effective mass. Furthermore, the large ionic radius of Pb2+ results in the
generation of additional point and plane defects and interphases, dramatically
enhancing phonon scattering, which significantly decreases the lattice thermal
conductivity at high temperatures. Overall, a maximum figure of merit (zTmax)
≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold
increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based
materials produced by solid-state, demonstrating advantages of versatility and
cost-effectiveness using a solution-based technology.

text: The direct, solid state, and reversible conversion between heat and electricity
using thermoelectric devices finds numerous potential uses, especially around
room temperature. However, the relatively high material processing cost limits
their real applications. Silver selenide (Ag2Se) is one of the very few n-type
thermoelectric (TE) materials for room-temperature applications. Herein, we report
a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se,
which can be extended to other metal chalcogenides. These materials reach TE figures
of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide
(Bi2S3) particles also prepared in an aqueous solution are incorporated into the
Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt %
of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering.
The presence of Bi2S3 significantly improves the Seebeck coefficient and power
factor while at the same time decreasing the thermal conductivity with no apparent
drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved
in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT
value (zTave) of 0.93 in the 300–390 K range is demonstrated.

text: AgSbSe2 is a promising thermoelectric (TE) p-type material for applications
in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal
conductivities and high Seebeck coefficients, but its main limitation is moderate
electrical conductivity. Herein, we detail an efficient and scalable hot-injection
synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier
concentration and improve the electrical conductivity, these NCs are doped with
Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using
a reducing NaBH4 solution to displace the organic ligand and anneal the material
under a forming gas flow. The TE properties of the dense materials obtained from
the consolidation of the NCs using a hot pressing are then characterized. The
presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier
concentration and, consequently, the electrical conductivity. Opportunely, the
measured Seebeck coefficient varied within a small range upon Sn doping. The excellent
performance obtained when Sn2+ ions are prevented from oxidation is rationalized
by modeling the system. Calculated band structures disclosed that Sn doping induces
convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic
effective mass. The dramatically enhanced carrier transport leads to a maximized
power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon
scattering is significantly enhanced in the NC-based materials, yielding an ultralow
thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of
merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above
the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and

text: The deployment of direct formate fuel cells (DFFCs) relies on the development
of active and stable catalysts for the formate oxidation reaction (FOR). Palladium,
providing effective full oxidation of formate to CO2, has been widely used as
FOR catalyst, but it suffers from low stability, moderate activity, and high cost.
Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn
nanoparticles. These nanoparticles are dispersed on carbon black and the obtained
composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based
electrodes present outstanding catalytic activities with record mass current densities
up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These
high current densities are further enhanced by increasing the temperature from
25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid
current decay that generally happens during operation and can be rapidly re-activated
through potential cycling. The excellent catalytic performance obtained is rationalized
using density functional theory (DFT) calculations.

text: The development of cost-effective, high-activity and stable bifunctional catalysts
for the oxygen reduction and evolution reactions (ORR/OER) is essential for zinc–air
batteries (ZABs) to reach the market. Such catalysts must contain multiple adsorption/reaction
sites to cope with the high demands of reversible oxygen electrodes. Herein, we
propose a high entropy alloy (HEA) based on relatively abundant elements as a
bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a
CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays
superior OER performance with an overpotential of 265 mV at a current density
of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard
commercial catalyst based on RuO2. This high performance is partially explained
by the presence of twinned defects, the incidence of large lattice distortions,
and the electronic synergy between the different components, being Cr key to decreasing
the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays
superior ORR performance with a half-potential of 0.78 V and an onset potential
of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the
OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking
advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi
HEA as air cathode and a zinc foil as the anode. The assembled cells provide an
open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a
peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that
stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8
mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.

text: SnSe has emerged as one of the most promising materials for thermoelectric
energy conversion due to its extraordinary performance in its single-crystal form
and its low-cost constituent elements. However, to achieve an economic impact,
the polycrystalline counterpart needs to replicate the performance of the single
crystal. Herein, we optimize the thermoelectric performance of polycrystalline
SnSe produced by consolidating solution-processed and surface-engineered SnSe
particles. In particular, the SnSe particles are coated with CdSe molecular complexes
that crystallize during the sintering process, forming CdSe nanoparticles. The
presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation
step due to Zener pinning, yielding a material with a high density of grain boundaries.
Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects
at different length scales, which significantly reduce the thermal conductivity.
The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit
up to 2.2 at 786 K, which is among the highest reported for solution-processed
SnSe.

text: A versatile, scalable, room temperature and surfactant-free route for the
synthesis of metal chalcogenide nanoparticles in aqueous solution is detailed
here for the production of PbS and Cu-doped PbS nanoparticles. Subsequently, nanoparticles
are annealed in a reducing atmosphere to remove surface oxide, and consolidated
into dense polycrystalline materials by means of spark plasma sintering. By characterizing
the transport properties of the sintered material, we observe the annealing step
and the incorporation of Cu to play a key role in promoting the thermoelectric
performance of PbS. The presence of Cu allows improving the electrical conductivity
by increasing the charge carrier concentration and simultaneously maintaining
a large charge carrier mobility, which overall translates into record power factors
at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity
decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room
temperature and ZT = 1.22 at 773 K. Besides, a record average ZTave = 0.76 is
demonstrated in the temperature range 320–773 K for n-type Pb0.955Cu0.045S.

text: Ligands are a fundamental part of nanocrystals. They control and direct nanocrystal
syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’
chemical reactivity and electronic structure. Surface chemistry is thus crucial
to understand nanocrystal properties and functionality. Here, we investigate the
synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate
precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals
are capped exclusively with a fatty acid instead of oleylamine. Analysis of the
reaction mixtures with nuclear magnetic resonance spectroscopy revealed several
reaction byproducts and intermediates that are common to the decomposition of
Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of
alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive
surface chemistry.

text: Solution synthesis of particles emerged as an alternative to prepare thermoelectric
materials with less demanding processing conditions than conventional solid-state
synthetic methods. However, solution synthesis generally involves the presence
of additional molecules or ions belonging to the precursors or added to enable
solubility and/or regulate nucleation and growth. These molecules or ions can
end up in the particles as surface adsorbates and interfere in the material properties.
This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically
adsorbed in SnSe particles synthesized in water and play a crucial role not only
in directing the material nano/microstructure but also in determining the transport
properties of the consolidated material. In dense pellets prepared by sintering
SnSe particles, Na remains within the crystal lattice as dopant, in dislocations,
precipitates, and forming grain boundary complexions. These results highlight
the importance of considering all the possible unintentional impurities to establish
proper structure-property relationships and control material properties in solution-processed
thermoelectric materials.

text: Composite materials offer numerous advantages in a wide range of applications,
including thermoelectrics. Here, semiconductor–metal composites are produced by
just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
and at room temperature with a metallic Cu powder. The obtained blend is annealed
in a reducing atmosphere and afterward consolidated into dense polycrystalline
pellets through spark plasma sintering (SPS). We observe that, during the annealing
process, the presence of metallic copper activates a partial reduction of the
PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
lead during the SPS process habilitates the liquid-phase sintering of the composite.
Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
that the presence of metallic lead decisively contributes to a strong increase
of the charge carrier concentration through spillover of charge carriers enabled
by the low work function of lead. The increase in charge carrier concentration
translates into much higher electrical conductivities and moderately lower Seebeck
coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
the presence of multiple phases in the final composite results in a notable decrease
in the lattice thermal conductivity. Overall, the introduction of metallic copper
in the initial blend results in a significant improvement of the thermoelectric
performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
= 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.
