Rational Design of Metal-Organic Framework-Based Materials for Photocatalytic CO2 Reduction

Photocatalytic carbon dioxide (CO2) reduction can utilize solar light to convert CO2 to high value-added products, which thus are recognized as an intriguing strategy to solve excessive CO2 emissions. Metal-organic framework (MOF)-based photocatalysts have shown high potential in the field of CO2 reduction due to their high porosity and tunable structure. In this review, the recent progress achieved in the rational design of MOF-based photocatalysts, including the pure MOF materials, MOF-based composites, and the derivatives of MOFs, for the reduction of CO2, are summarized and the developed modification strategies to enhance the photocatalytic performance of MOF-based photocatalysts are highlighted. The current pending issues and the outlook for the future development are also discussed.
