Ru–Na₂ZrO₃ DFMs, obtained through different wet methods, were evaluated for the first time and the relationship between Ru and support systematically investigated. The thermally stable and cyclable Ru–Na₂ZrO₃-a (obtained without filtration step) exhibited CO₂ conversion of 80 % and a higher yield of CO at 400 °C compared to previously tested DFM, while the Na depleted/Zr rich Ru–Na₂ZrO₃-b resulted in 90 % selectivity to CH₄ with yield of 1.11 mmol/g at the same temperature. The in-situ experiments have provided conclusive evidence showing that CO₂ hydrogenation on the two Ru DFMs is fundamentally different. In Ru–Na₂ZrO₃-a, the monoclinic Na₂ZrO₃ support acted as the active centre (not as promoter) for CO₂ bridging binding and hydrogenation to CH₄ at the metal-support interface through associative formate pathway with limited further reduction to methane due to lack of H₂ spillover from the small and well dispersed Ru NPs, which results in CO desorption. Conversely, abundant clusters of larger Ru NPs in Ru–Na₂ZrO₃-b, led to CH₄ production due to co-existent Ru on-top direct dissociation of CO₂ (preferential) and monodentate formate adsorption and further methanation. Alkali zirconates doped metals, and their synthesis method could thus play a crucial role in designing tuneable heterogeneous catalysis in C₁ chemistry, which could significantly benefit the environment by lowering CO₂ levels, encouraging cleaner industrial practices, supporting a circular economy, and converting waste CO₂ into valuable products.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"121 ","pages":"Pages 118-131"},"PeriodicalIF":8.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, massive endeavors are done lately to develop sustainable processes for hydrogen generation. Among those methods, hydrogen production through photocatalytic aqueous reforming of methanol coupled with water splitting is considered one of the most efficient sustainable routes. In line with this methodology, the current research study introduces two novel photocatalysts (CoCe-MOF and its composite with reduced graphene oxide) for hydrogen generation from a water-methanol mixture. The textural, morphological, optical, and structural characteristics of the prepared materials were verified through various analytical techniques. Both structures revealed reasonable hydrogen productivity; however, the composite-MOF showed increased reactivity. The composition of the produced gases upon using both structures varied significantly. The explicit differences in the activities of both photocatalysts are attributed to the presence of graphene species in the composite-MOF. Statistical modeling was employed to comprehensively design the hydrogen production experiments based on preliminary experimental results that were obtained under different operating variables. A maximum hydrogen productivity of 560 mmol h⁻¹ g⁻¹, along with a hydrogen percentage of 60 % in the produced gas, was detected for the composite-MOF under a reaction time of 1.5 h, 4 g/L as a photocatalyst dose, and a radiation power equals 3 W cm². Both the model predictions and practical investigations were in agreement, showing that the photocatalyst dose and operating time are the most influential parameters in the hydrogen generation process. Furthermore, the recyclability of the composite photocatalyst was evaluated over six consecutive cycles under optimized conditions, confirming its increased stability. This excellent stability demonstrates the potential of the composite-MOF for long-term hydrogen production applications, reflecting the feasibility of its usage as efficient/reusable photocatalyst.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"121 ","pages":"Pages 79-95"},"PeriodicalIF":8.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
