To overcome this constraint, several approaches to integrating MOFs with light-responsive semiconductors have been investigated. This study used a Zr-based MOF with ZnCo<sub>2</sub>O<sub>4</sub> to create a highly effective photocatalyst. The goal was to improve charge separation and photocatalytic performance. The resultant composite demonstrated exceptional degradation efficiencies of 82.27% for Bismarck Brown (BB) and 94.24% forRose Bengal (RB) under natural sunlight within 55 min, with optimal catalyst doses of 0.47 g/L. The composite's structural, morphological and optical properties were fully investigated utilising SEM–EDX, HRTEM, PXRD, FTIR, XPS, BET and UV-DRS techniques. The photodegradation process followed first-order kinetics, with rate constants of 0.0371 min<sup>−1</sup> and 0.06544 min<sup>−1</sup> for BB and RB, respectively. Photoluminescence (PL) spectroscopy, VB-XPS and scavenger quenching investigations provided mechanistic insights into successful charge separation and reactive species formation. The ZnCo<sub>2</sub>O<sub>4</sub>@UiO-66 composite is highly recyclable, with consistent XRD patterns confirming stable photocatalytic efficacy across five cycles. These findings emphasise the composite's potential as a strong and reusable MOF-based photocatalyst for efficiently removing dye contaminants in environmental remediation applications.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"40 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
