Beyond catalyst micro-design, system macro-modulation of CO2 electrolysis still lacks development, limiting its commercial implementation. Here, we designed a B-site-engineered high-entropy perovskite, Sr2Fe0.8Mo0.4Co0.2Ni0.2Cu0.2Ru0.2O6−δ (SFMCNCR), and implemented it in a cascaded SOEC system. Computational calculations reveal that high-entropy B-site doping lowers the oxygen vacancy formation energy and strengthens the Fe 3d–O 2p orbital hybridization, thereby facilitating CO2 adsorption and activation. This is verified by experimental results that oxygen-vacancy-rich SFMCNCR delivers a high current density of 2.08 A cm−2 and a CO Faradaic efficiency of 96.18% at 1.5 V and 850°C. Notably, the cascaded dual-SOEC configuration achieved a CO production rate of 32.25 mL min−1 cm−2 and a conversion rate exceeding 44%.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"1 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146205571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, PFeMo polyoxometalate nanoparticles embedded into a BiVO4 (bismuth vanadate [BVO]) photoanode boost the photon utilization efficiency by employing a novel strategy of enhancing the interfacial electric field and broadening light absorption pathways. Additionally, it can accelerate hole extraction by facilitating the dissociation of self-trapped excitons and reducing transmission voltage loss to achieve efficient charge separation. As a result, the BVO/PFeMo/NiFeOx photoanode demonstrates light absorption exceeding 90% in the 300–450 nm wavelength range, with charge separation efficiency approaching 100% at 1.23 VRHE. Furthermore, a perovskite solar cell with photoanodes in tandem delivers a remarkable solar-to-hydrogen efficiency of 7.23%. Overall, this work proposes a new light absorption strategy on the basis of increasing BVO charge carrier separation, providing a new perspective for further improving the performance of photoanodes.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":"242 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146160920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
