Development of high performing UiO-67/BiFeO3 photocatalyst for selective CO2 conversion to methanol: Process optimization by RSM
The continuous rise in atmospheric CO2 levels due to industrialization has raised pressing environmental concerns, necessitating efficient carbon capture and utilization strategies. Among them, the photocatalytic reduction of CO2 to methanol offers a sustainable approach that mitigates emissions while producing a valuable solar fuel. Metal-organic frameworks (MOFs) have emerged as promising photocatalysts due to their high surface area, tunable porosity, and dense active sites, though their wide bandgaps limit visible-light activity. In this study, a UiO-67/BiFeO3 composite photocatalyst was synthesized via a wet chemical method, combining BiFeO3's narrow bandgap with the structural advantages of UiO-67. Photocatalytic tests under visible light showed a significant improvement in methanol production, with the composite achieving 93.99 μmol/g·h after 4 h outperforming pure UiO-67 (31.29 μmol/g·h) and BiFeO3 (8.01 μmol/g·h). To optimize reaction conditions, Response Surface Methodology (RSM) and Box–Behnken design (BBD) were employed. The resulting model (R2 = 0.9966) identified an optimal methanol production rate of 95.06 μmol/g·h with a desirability value of 1.000. These findings highlight the synergistic role of BiFeO3's light absorption and UiO-67's CO2 adsorption, showcasing the potential of RSM in optimizing MOF-based photocatalytic systems for sustainable CO2 conversion.
期刊介绍:
Sustainable Chemistry and Pharmacy publishes research that is related to chemistry, pharmacy and sustainability science in a forward oriented manner. It provides a unique forum for the publication of innovative research on the intersection and overlap of chemistry and pharmacy on the one hand and sustainability on the other hand. This includes contributions related to increasing sustainability of chemistry and pharmaceutical science and industries itself as well as their products in relation to the contribution of these to sustainability itself. As an interdisciplinary and transdisciplinary journal it addresses all sustainability related issues along the life cycle of chemical and pharmaceutical products form resource related topics until the end of life of products. This includes not only natural science based approaches and issues but also from humanities, social science and economics as far as they are dealing with sustainability related to chemistry and pharmacy. Sustainable Chemistry and Pharmacy aims at bridging between disciplines as well as developing and developed countries.
