In a plurality of CO 2 In the conversion process, photocatalysis is considered to be the most reasonable CO due to no secondary energy consumption 2 One of the transformation paths, to develop and design a stable and high-efficiency CO 2 Reducing the photocatalyst is often the key. Crystalline porous framework materials due to their excellent light absorptionThe advantages of capability, larger specific surface area, adjustable frame structure and the like in photocatalysis of CO 2 The reduction field shows a larger application value. However, the photocatalytic activity of the crystalline porous framework material is seriously affected by the low electron utilization rate caused by the high recombination rate of electron-hole pairs in the photocatalytic process.

Currently, COFs have become a new class of visible light responsive catalysts. COF-316 is a complex vector with great development potential. Therefore, the method proposes that Nafion polymer is loaded into COF-316 pore channels, and the synergistic effect of COFs and Nafion polymer is utilized to improve the proton transmission capability, so that the photocatalytic activity of the photocatalyst is improved.
