共价有机框架材料催化研究进展

共价有机框架材料(COFs)是一类具有高比表面积、高孔隙率、高结晶度的结构多样性多孔材料.由于COFs具有可设计性、易功能化的特点,可通过"自上而下"或者后修饰策略将具有催化活性的官能团或金属颗粒嵌入到材料骨架当中,从而设计出高效催化剂. COFs已逐渐在多相催化及其它催化领域展现出非常大的应用价值.本文综述了COFs作为催化剂载体在多种催化反应中的合成策略与应用,对COFs催化剂的现状进行了总结与展望,同时指出该领域面临的问题与挑战.

Research Progress of Covalent Organic Framework Materials in Catalysis

Covalent organic framework materials(COFs) are a class of organic porous materials with large specific surface area, high porosity and crystallinity. Owning to their special nature of functional versatility and easy modification, COFs can be designed to be efficient catalysts either embed functional active sites into the skeleton through a "top-down" strategy, or load metal nanoparticles into the framework via a post-modification approach. These studies have laid the foundation for the extension of COF’s application in heterogeneous and other catalytic fields. The synthetic strategy and application of COF in different types of catalytic reactions are reviewed in this paper. Moreover, the current research situation of COF catalyst is summarized and prospected. Finally, the remaining challenges in this field are also indicated.
