The invention discloses a CO2 reduction photoelectric catalyst, and a preparation method thereof, and belongs to the field of photoelectrocatalysis. The CO2 reduction photoelectric catalyst is graphene oxide coated MAPbBr3. The preparation method comprises following steps: firstly, MABr and PbBr2 are dissolved in a graphene dimethyl formamide solution, oleic acid and oleylamine are added for fullstirring to prepare a pre-prepared solution, the pre-prepared solution is added into a toluene solution at 40 to 80 DEG C for reaction, and at last, a toluene and acetonitrile mixed solution is addedinto a mixed solution containing reaction products, and centrifugation treatment is carried out so as to obtain a precipitate. The technology is simple and controllable; pollution is low; and the prepared graphene oxide coated MAPbBr3 possesses excellent photoelectric catalysis performance on CO2. 本发明公开了一种CO还原光电催化剂及其制备方法，属于光电催化领域，该催化剂为氧化石墨烯包覆的MAPbBr。本发明还公开了制备该催化剂的方法，首先，将MABr与PbBr溶于氧化石墨烯的二甲基甲酰胺溶液中，接着加入油酸与油胺后充分搅拌，制成预制溶液，接着，向
