Abstract

The application discloses a preparation method and application of a high-energy electron beam irradiation induced functionalized hydrogen bond organic framework photocatalyst, and belongs to the technical field of new environmental catalysis materials. Zinc salt and a hydrogen bond organic framework are added into an isopropanol solution, stirred uniformly, sealed, and then N2 is introduced. The mixed solution is irradiated through high-energy electron beam irradiation. The mixed solution after high-energy electron beam irradiation is cleaned through ethanol centrifugation to obtain the high-energy electron beam irradiation induced functionalized hydrogen bond organic framework catalyst. The preparation method of the high-energy electron beam irradiation induced functionalized hydrogen bond organic framework catalyst has the advantages of relatively simple operation, low cost, and large-batch preparation. The high-energy electron beam irradiation induced functionalized hydrogen bond organic framework catalyst prepared by the application has excellent performance in the photocatalytic reduction of CO2 into CO under full spectrum and CO2 atmosphere.
