In this study, we report the integration of Cu-based metal-organic framework (MOF) electrocatalysts into gas diffusion layers (GDLs) to enhance CO<sub>2</sub>RR performance. Electrocatalysts, specifically Cu/ZnO-UiO66 and Cu/ZnO-MDC, were deposited onto GDLs using an air-spraying technique, ensuring a homogeneous distribution of active metals across the substrate. Comprehensive characterisation of the modified GDLs was performed using field-emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (FESEM-EDX), X-ray diffraction (XRD), and tensiometer to assess surface morphology, textural properties, and phase composition, respectively. The deposition process resulted in a notable increase in hydrophilicity compared to pristine GDLs, as indicated by reduced contact angles.

Even after eight consecutive adsorption-desorption cycles, the regeneration rate of the composite material remained above 97 %, demonstrating complete regenerability. Factors enhancing the material's dynamic adsorption capacity for CO<sub>2</sub> include the presence of micropores, Cu<sup>2+</sup>'s affinity for CO<sub>2</sub>, and the imbalance of surface electrostatics due to Cu<sup>2+</sup> and Zn<sup>2+</sup> exchange. However, when Cu<sup>2+</sup>:Zn<sup>2+</sup> exceeds 0.25:1, a large amount of Cu-BDC is generated, leading to a rapid decline in the material's adsorption performance. The obtained adsorbent parameters indicate that Cu-MOF-5 material is a promising CO<sub>2</sub> adsorbent.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"31 ","pages":"Article 101181"},"PeriodicalIF":7.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662249","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}
