Here we demonstrated the fabrication of FeCoP hollow nanocubes by precisely controlling the oxidation-phosphorization processing on Prussian blue analogues. Owing to the robust electronic interaction and hollow structure, the obtained FeCoP material, when utilized for catalyzing HER and OER in a 1 M KOH solution, requires overpotentials of merely 74 mV and 219 mV to achieve 10 mA cm−2, respectively. Importantly, when used as a bifunctional catalyst for overall water splitting, FeCoP can achieve a current density of 10 mA cm−2 at a low cell voltage of only 1.58 V and exhibits impressive durability. After a prolonged test of 52 hours under a constant current density, there is no significant degradation performance decay. The current method offers a broader avenue for the controllable synthesis of phosphide electrocatalysts in practical applications.","PeriodicalId":11668,"journal":{"name":"Electrochemistry","volume":"93 1","pages":"017004-017004"},"PeriodicalIF":0.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147897546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work offers insights into the interaction between solid AlPO4 and molten CaCl2. The results show that solid AlPO4 exhibits favorable solubility in molten CaCl2, although at a slower rate compared to solid Ca3(PO4)2 due to the presence of stable Al–O bonds. The study also demonstrates the feasibility of extracting high-purity P4 from the molten mixture through electrolysis. The purity of the obtained electrolyzed P4 from AlPO4 is comparable to the commercially available high-purity-grade product. These findings underscore the potential of sewage sludge ash containing AlPO4 as a viable source for extracting high-purity P4. This research contributes to the advancement of sustainable P utilization technologies from secondary sources.","PeriodicalId":11668,"journal":{"name":"Electrochemistry","volume":"92 4","pages":"043015-043015"},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.jstage.jst.go.jp/article/electrochemistry/advpub/0/advpub_24-69001/_pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
