Among different chalcogenides, while Cu2−xSe is characterized by higher thermoelectric figures of merit, Cu2−xS provides advantages in terms of low cost and element abundance. In the present work, we investigate the effect of different dopants to enhance the Cu2−xS performance and also its thermal stability. Among the tested options, Pb-doped Cu2−xS shows the highest improvement in stability against sulfur volatilization. Additionally, Pb incorporation allows tuning charge carrier concentration, which enables a significant improvement of the power factor. We demonstrate here that the introduction of an optimal additive amount of just 0.3% results in a threefold increase of the power factor in the middle-temperature range (500–800 K) and a record dimensionless thermoelectric figure of merit above 2 at 880 K.","lang":"eng"}],"language":[{"iso":"eng"}],"publication":"Nano Energy","project":[{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"oa_version":"Submitted Version","article_number":"105991","month":"07","main_file_link":[{"open_access":"1","url":"https://ddd.uab.cat/record/271947"}],"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","date_published":"2021-07-01T00:00:00Z","publication_identifier":{"issn":["2211-2855"]},"oa":1},{"acknowledgement":"This work was supported by the European Regional Development Funds and by the Spanish Ministerio de Economía y Competitividad through the project SEHTOP, ENE2016- 77798-C4-3-R, and ENE2017-85087-C3.

In this work, we engineer a new electrocatalyst by incorporating phosphorous into a palladium-tin alloy and demonstrate a significant performance improvement toward EOR. We first detail a synthetic method to produce Pd2Sn:P nanocrystals that incorporate 35% of phosphorus. These nanoparticles are supported on carbon black and tested for EOR. Pd2Sn:P/C catalysts exhibit mass current densities up to 5.03 A mgPd−1, well above those of Pd2Sn/C, PdP2/C and Pd/C reference catalysts. Furthermore, a twofold lower Tafel slope and a much longer durability are revealed for the Pd2Sn:P/C catalyst compared with Pd/C. The performance improvement is rationalized with the aid of density functional theory (DFT) calculations considering different phosphorous chemical environments. Depending on its oxidation state, surface phosphorus introduces sites with low energy OH− adsorption and/or strongly influences the electronic structure of palladium and tin to facilitate the oxidation of the acetyl to acetic acid, which is considered the EOR rate limiting step. DFT calculations also points out that the durability improvement of Pd2Sn:P/C catalyst is associated to the promotion of OH adsorption that accelerates the oxidation of intermediate poisoning COads, reactivating the catalyst surface.","lang":"eng"}],"quality_controlled":"1","publisher":"Elsevier","article_type":"original","scopus_import":"1","_id":"8189","issue":"11","author":[{"first_name":"Xiaoting","last_name":"Yu","full_name":"Yu, Xiaoting"},{"first_name":"Junfeng","last_name":"Liu","full_name":"Liu, Junfeng"},{"full_name":"Li, Junshan","first_name":"Junshan","last_name":"Li"},{"full_name":"Luo, Zhishan","first_name":"Zhishan","last_name":"Luo"},{"full_name":"Zuo, Yong","first_name":"Yong","last_name":"Zuo"},{"last_name":"Xing","first_name":"Congcong","full_name":"Xing, Congcong"},{"last_name":"Llorca","first_name":"Jordi","full_name":"Llorca, Jordi"},{"full_name":"Nasiou, Déspina","last_name":"Nasiou","first_name":"Déspina"},{"first_name":"Jordi","last_name":"Arbiol","full_name":"Arbiol, Jordi"},{"full_name":"Pan, Kai","last_name":"Pan","first_name":"Kai"},{"id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425","full_name":"Kleinhanns, Tobias","last_name":"Kleinhanns","first_name":"Tobias"},{"last_name":"Xie","first_name":"Ying","full_name":"Xie, Ying"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"date_created":"2020-08-02T22:00:57Z","article_processing_charge":"No","department":[{"_id":"MaIb"}],"publication_status":"published","intvolume":"        77","title":"Phosphorous incorporation in Pd2Sn alloys for electrocatalytic ethanol oxidation","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","type":"journal_article","date_published":"2020-11-01T00:00:00Z","publication_identifier":{"issn":["2211-2855"]},"language":[{"iso":"eng"}],"publication":"Nano Energy","oa_version":"None","article_number":"105116","month":"11"}]
