Abstract:

Covalent organic frameworks (COFs), established as an emerging class of crystalline porous poly-mers with high surface area, structural diversity, and designability, attract much interest and exhibit potential applications in catalysis. In this review, we summarize the use of COFs as a versatile plat-form to develop heterogeneous catalysts for a variety of chemical reactions. Catalytic COFs are cat-egorized in accordance with the types of active sites, involving single functional active sites, bifunc-tional active sites, and metal nanoparticles (NPs) embedded in pores. Special emphasis is placed on the deliberate or incidental synthesis strategies, the stability, the heterogeneity, and the shape/size selectivity for COF catalysis. Moreover, a description of the application of COFs as photocatalysts and electrocatalysts is presented. Finally, the prospects of COFs in catalysis and remaining issues in this field are indicated.
