Non-metallic alloying of Pt has become an emerging strategy to improve electrocatalytic performance, however, the electrocatalytic ORR mechanisms still need to be understood for further improvement toward practical application. Herein, a rapid microwave reduction method is employed for alloying phosphorous (P) into Pt to form a carbon supported phosphorus-alloyed Pt nanoparticle catalyst (P-Pt/C), which demonstrates the ability to replace commercial Pt/C. By a combination of density functional theory calculations and <em>in-situ</em> electrochemical Raman spectroscopy, the regulation role of P-alloying in the electrocatalytic mechanisms is revealed. It is found that the nearby Pt atoms can convert the ORR pathway from associative one to dissociative one, exhibiting a spontaneous dissociation of *OOH intermediate to *OH and *O species as well as a change of potential determining step to *O protonation. Furthermore, the strategy of large-scale economic synthesis of such alloying Pt-based catalyst is also established, demonstrated by a gram-level synthesis per batch. This study puts insight into the electrocatalytic ORR fundamentals of Pt-alloying with non-metals and provides a basis for the reasonable design and synthesis of efficient nonmetals-alloyed Pt catalysts.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 4","pages":"Article 110789"},"PeriodicalIF":9.4,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143149460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, dual-defect engineering strategy is implemented by introducing boron-doping and phosphorus-vacancy sites with MoP@NC composite as the precursor. Based on the experimental characterizations and theoretical calculations, B-MoP<sub>1-x</sub>@NC-based electrode presents low oxidation potential, high lithium diffusivity, small Tafel slope and strong adsorption capability for polysulfides, which is beneficial to enhance the adsorption capability for LiPSs, reduce the lithium diffusion energy barriers and Gibbs free energy for the conversion reactions of LiPSs. As demonstrated, the corresponding Li-S/B-MoP<sub>1-x</sub>@NC batteries can remain high reversible capacity of 753 mAh/g at 0.5 C after 300 cycles, and keep a stable capacity of 520 mAh/g at 0.5 C after 100 cycles even at the high-loading content of 5.1 mg/cm<sup>2</sup>. According to the results of in-situ UV–vis spectra, the satisfactory battery performance majorly originates from the existence of dual-defect characteristics in B-MoP<sub>1-x</sub>@NC catalyst, which effectively promotes the conversion reaction kinetics of LiPSs, and restrains the shuttle behavior of LiPSs. The key ideas of this work will enlighten the development of catalytic cathode materials for sulfur-based secondary batteries.</div></div>","PeriodicalId":10088,"journal":{"name":"Chinese Chemical Letters","volume":"36 3","pages":"Article 110731"},"PeriodicalIF":9.4,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143318148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
