Emerging applications of porous organic polymers in visible-Light photocatalysis

Abstract

Porous organic polymers (POPs) are emerging porous solids featuring high porosity, low density, diverse composition, facile functionalization, and high thermal/chemical stability. POPs are proven competitive candidates in various applications, such as storage/separation, energy storage, biomedical applications, optical device, and catalysis. Photocatalysis enables multifarious transformations of chemicals under mild conditions without enormous energy consumption and contaminant generation. Catalytically active species can be incorporated into POPs by means of covalent bonding or metal–ligand coordination, and the catalytic power of POPs can be fine tuned by modulating electronic properties of monomers and pore structures of the solids, which make the POPs-based heterogeneous photocatalyst designable for task-specific applications. The outstanding performance and reusability distinguish POPs from homogeneous analogues. As a result, the catalytic efficiency can be significantly enhanced and cost would be considerably reduced. In this review, we aim to highlight the recent researches of POPs in visible-light-driven photocatalysis, including organic synthesis, hydrogen evolution, carbon dioxide reduction, and degradation of organic pollutants. Technological concerns on hindrance of preparation, post processing, performance optimization, cost and energy consumption are also discussed.
