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.

Metal–organic frameworks (MOFs) have garnered significant attention for water purification in recent years. In particular, UiO-66 (a member of the UiO-MOF family, developed at University Oslo) has emerged as a promising material. exhibits excellent adsorption through electrostatic interaction, π–π stacking and Lewis acid–base coordination mechanisms. The photocatalytic degradation property was enhanced metal doping, composite with semiconductor materials, defect engineering, etc., removal efficiency pollutants significantly improved. This review systematically describes structure synthesis methods UiO-66, including solvothermal, microwave-assisted, mechanized electrochemical methods, well application various pollutants.
