▎ 摘  要

NOVELTY - Preparation method of the photocatalyst modified by the covalent bond between 2-aminoterephthalate oxygen zirconium tetrahydroxide (UiO-66-NH2) and reduced graphene oxide (RGO) interface comprises dissolving zirconium chloride and 2-aminoterephthalic acid in N,N-dimethylformamide, then adding acetic acid, transferring the mixture to an autoclave lined with Teflon, and and obtain UiO-66-NH2 through solvothermal reaction. Dispersing graphene oxide (GO) uniformly in deionized water to obtain GO suspension. Reacting UiO-66-NH2, ascorbic acid and GO suspension hydrothermally. USE - Preparation method of the photocatalyst used for carbon dioxide conversion to carbon monoxide. ADVANTAGE - 2-aminoterephthalate oxygen zirconium tetrahydroxide/reduced graphene oxide photocatalytic system connected by covalent bonds at the interface through a simple preparation method, which promotes electron transfer at the interface, shortens the migration path of photogenerated electrons, improves the utilization rate of electrons, and accelerates rate at which carbon dioxide is converted to carbon monoxide.
