Covalent Organic Framework Based Functional Materials: Important Catalysts for Efficient CO Utilization.

As hot topics in the chemical conversion of CO , the photo-/electrocatalytic reduction of CO and use of CO as a supporter for energy storage have shown great potential for the utilization of CO . However, many obstacles still exist on the road to realizing highly efficient chemical CO conversion, such as inefficient uptake/activation of CO and mass transport in catalysts. Covalent organic frameworks (COFs), as a kind of porous material, have been widely explored as catalysts for the chemical conversion of CO owing to their unique features. In particular, COF-based functional materials containing diverse active sites (such as single metal sites, metal nanoparticles, and metal oxides) offer great potential for realizing CO conversion and energy storage. This Minireview discusses recent breakthroughs in the basic knowledge, mechanisms, and pathways of chemical CO conversion strategies that use COF-based functional catalysts. In addition, the challenges and prospects of COF-based functional catalysts for the efficient utilization of CO are also introduced.
