Nevertheless, systematic bibliometric analyses of its developmental trajectories remain scarce. A comprehensive, in-depth examination—encompassing evolving research focus, influential scholars, and the broader landscape of advancement—is therefore imperative to provide robust, evidence-based guidance for future investigations. We collected relevant literature on photocatalytic overall water splitting indexed in the Web of Science Core Collection between 2015 and 2025. Using CiteSpace software, this approach enabled us to pinpoint current thematic hotspots and leading contributors in the field. Furthermore, we performed focused case studies on four representative photocatalytic materials—TiO2, C3N4, SrTiO3, and BiVO4—to quantitatively assess their publication outputs, author contributions, institutional collaborations, and cocitation patterns. These analyses collectively illuminate prevailing research emphases and emerging directions in photocatalytic water-splitting material design and optimization. By integrating advanced bibliometric methodologies with domain-specific scholarly insight, this study establishes a methodologically sound framework for literature synthesis and knowledge mapping in overall photocatalytic water splitting. The findings offer a novel, data-informed perspective on the state and trajectory of photocatalytic overall water splitting research—and thereby support its accelerated scientific and technological advancement.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 5","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we develop a self-floating photocatalyst, Pt@MBP, consisting of platinum (Pt) nanoparticles anchored on triazine-biphenyl conjugated polymer nanosheets. Pt@MBP is prepared through calcination of a melamine-biphenyl-4,4′-dicarboxylic acid supramolecular precursor followed by photodeposition of Pt. Owing to its floatable feature, Pt@MBP effectively captures atmospheric O2 at the gas–liquid interface and enhances visible-light harvesting. The ultrathin MBP nanosheets facilitate charge separation and migration, while the well-dispersed Pt nanoparticles function as electron sinks and catalytic centers for O2 adsorption and activation, thereby lowering the energy barrier for the oxygen reduction (ORR) pathway. As a result, Pt@MBP achieves a H2O2 production rate of 2352 μmol g−1 h−1 in pure water. This work establishes a rational design of self-floating polymer photocatalysts for efficient solar-to-chemical conversion.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"10 5","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
