In this scenario, the implementation of lithium sulfide (Li2S) cathodes compatible with alternative anode materials such as silicon has the potential to alleviate the safety concerns associated with lithium metal. In this direction, here, we report a sulfur cathode based on Li2S nanocrystals grown on a catalytic host consisting of CoFeP nanoparticles supported on tubular carbon nitride. Nanosized Li2S is incorporated into the host by a scalable liquid infiltration–evaporation method. Theoretical calculations and experimental results demonstrate that the CoFeP–CN composite can boost the polysulfide adsorption/conversion reaction kinetics and strongly reduce the initial overpotential activation barrier by stretching the Li–S bonds of Li2S. Besides, the ultrasmall size of the Li2S particles in the Li2S–CoFeP–CN composite cathode facilitates the initial activation. Overall, the Li2S–CoFeP–CN electrodes exhibit a low activation barrier of 2.56 V, a high initial capacity of 991 mA h gLi2S–1, and outstanding cyclability with a small fading rate of 0.029% per cycle over 800 cycles. Moreover, Si/Li2S full cells are assembled using the nanostructured Li2S–CoFeP–CN cathode and a prelithiated anode based on graphite-supported silicon nanowires. These Si/Li2S cells demonstrate high initial discharge capacities above 900 mA h gLi2S–1 and good cyclability with a capacity fading rate of 0.28% per cycle over 150 cycles.","lang":"eng"}],"day":"05","doi":"10.1021/acsami.3c14072","year":"2023","citation":{"chicago":"Mollania, Hamid, Chaoqi Zhang, Ruifeng Du, Xueqiang Qi, Junshan Li, Sharona Horta, Maria Ibáñez, et al. “Nanostructured Li₂S Cathodes for Silicon-Sulfur Batteries.” <i>ACS Applied Materials and Interfaces</i>.

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."}],"doi":"10.1021/acsami.1c15609","day":"19","language":[{"iso":"eng"}],"keyword":["CuxS","PbS","energy conversion","nanocomposite","nanoparticle","solution synthesis","thermoelectric"],"publication":"ACS Applied Materials and Interfaces","month":"10","oa_version":"Submitted Version","project":[{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"}],"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"https://upcommons.upc.edu/bitstream/2117/363528/1/Pb%20mengyao.pdf"}],"date_published":"2021-10-19T00:00:00Z","type":"journal_article","oa":1,"publication_identifier":{"issn":["1944-8244"],"eissn":["1944-8252"]}},{"title":"Electron-deficient near-infrared Pt(II) and Pd(II) benzoporphyrins with dual phosphorescence and unusually efficient thermally activated delayed fluorescence: First demonstration of simultaneous oxygen and temperature sensing with a single emitter","intvolume":"         9","publication_status":"published","date_created":"2020-01-15T12:15:16Z","article_processing_charge":"No","author":[{"last_name":"Zach","first_name":"Peter W.","full_name":"Zach, Peter W."},{"id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","last_name":"Freunberger","first_name":"Stefan Alexander","full_name":"Freunberger, Stefan Alexander","orcid":"0000-0003-2902-5319"},{"last_name":"Klimant","first_name":"Ingo","full_name":"Klimant, Ingo"},{"full_name":"Borisov, Sergey M.","first_name":"Sergey M.","last_name":"Borisov"}],"issue":"43","_id":"7290","article_type":"original","publisher":"ACS","file_date_updated":"2020-07-14T12:47:55Z","page":"38008-38023","quality_controlled":"1","abstract":[{"text":"We report a family of Pt and Pd benzoporphyrin dyes with versatile photophysical properties and easy access from cheap and abundant chemicals. Attaching 4 or 8 alkylsulfone groups onto a meso-tetraphenyltetrabenzoporphyrin (TPTBP) macrocylcle renders the dyes highly soluble in organic solvents, photostable, and electron-deficient with the redox potential raised up to 0.65 V versus the parent porphyrin. The new dyes intensively absorb in the blue (Soret band, 440–480 nm) and in the red (Q-band, 620–650 nm) parts of the electromagnetic spectrum and show bright phosphorescence at room-temperature in the NIR with quantum yields up to 30% in solution. The small singlet–triplet energy gap yields unusually efficient thermally activated delayed fluorescence (TADF) at elevated temperatures in solution and in polymeric matrices with quantum yields as high as 27% at 120 °C, which is remarkable for benzoporphyrins. Apart from oxygen sensing, these properties enable unprecedented simultaneous, self-referenced oxygen and temperature sensing with a single indicator dye: whereas oxygen can be determined either via the decay time of phosphorescence or TADF, the temperature is accessed via the ratio of the two emissions. Moreover, the dyes are efficient sensitizers for triplet–triplet annihilation (TTA)-based upconversion making possible longer sensitization wavelength than the conventional benzoporphyrin complexes. The Pt-octa-sulfone dye also features interesting semireversible transformation in basic media, which generates new NIR absorbing species.","lang":"eng"}],"doi":"10.1021/acsami.7b10669","day":"10","date_updated":"2021-01-12T08:12:48Z","year":"2017","citation":{"ista":"Zach PW, Freunberger SA, Klimant I, Borisov SM. 2017.
