The ternary composite was prepared by incorporating an optimized 40 %-SrTiO₃/g-C₃N₄ (STC) binary mixture onto ZnO nanoparticles, and its performance was systematically evaluated. The optimal 35 %-STCZ nanocomposite demonstrated a remarkable hydrogen evolution rate of 603.94 μmol·g⁻¹·h⁻¹, representing a twofold increase compared to the STC binary photocatalyst. Furthermore, it achieved a 96 % TC degradation efficiency under the following optimized conditions: catalyst dosage of 0.65 g/L, TC concentration of 28.24 mg/L, reaction time of 71.98 min, and pH 5.11. Comprehensive material characterization, including XRD, XPS, SEM, TEM, BET, and UV–vis DRS analyses, confirmed the successful synthesis and enhanced photocatalytic properties of the 35 %-STCZ composite. Moreover, EIS, PL spectroscopy, and photocurrent measurements indicated efficient charge separation and improved carrier mobility, attributed to the dual <em>Z</em>-scheme heterojunction mechanism. Trapping experiments and ESR analysis revealed that hydroxyl (•OH) and superoxide (•O₂⁻) radicals played pivotal roles in the photocatalytic degradation of TC, with intermediate degradation pathways elucidated via LC-MS analysis. Toxicity assessments demonstrated that the photocatalytic treatment significantly reduced the ecological impact of TC and its byproducts. The 35 %-STCZ composite exhibited excellent stability, maintaining 85 % of its photocatalytic activity over five consecutive cycles for TC degradation. Additionally, the catalyst performed effectively across diverse water sources, underscoring its practical applicability. These findings highlight the potential of the SrTiO₃/g-C₃N₄/ZnO photocatalyst for dual applications in environmental remediation and sustainable hydrogen production, offering a promising pathway toward carbon-neutral energy solutions and water pollution control.</div></div>","PeriodicalId":316,"journal":{"name":"FlatChem","volume":"50 ","pages":"Article 100841"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143561923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we employed density functional theory modelling to systematically reveal the general mechanism behind this trapping strategy with the different sizes of micropores and metal complex anions. The results demonstrate that the carbon micropores can well trap the metal complex anions with the similar size and shape, since the micropore trapping effect comes from the synergism of the van der Waals force relating to the number of involved atoms and the electrostatic interaction from N dopants. The captured complex anions gradually get reduced at the micropores, and the final coordination is related to the reduction condition and the ligands of the complex anions. The deep theoretical insight into this strategy provides a new route to design the advanced SSCs by tuning the size and shape of carbon micropores to match the targeted metal complex anions, and regulating the ligands and reduction conditions to control the coordination environment.</div></div>","PeriodicalId":316,"journal":{"name":"FlatChem","volume":"50 ","pages":"Article 100840"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143534500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
