The substantial release of industrial carbon dioxide has been identified as a key factor in the development various environmental issues. In addressing these concerns, utilization photocatalytic technology for reduction garnered significant attention. disadvantage CO2 photoreduction is problem product yield and selectivity. It known that MIL-125(Ti) with high specific surface area (SBET) possesses more active sites using Ti node. calcination reducing atmosphere shown to introduce oxygen vacancies (OV), thereby enhancing material’s internal pores. This process demonstrated result increase SBET an enhancement Ti3+/Ti4+ ratio. increased Ti3+ centers have found improve properties. results demonstrate OV-rich MIL-125-2H material exhibits high-performance highly selective CO2.
