Preparation method and application of ZnO-Cu2O-AC photocatalyst

The invention relates to a preparation method and application of a ZnO-Cu2O-AC photocatalyst, and belongs to the technical field of photo-catalysis. The preparation method comprises the following steps: preparing a catalyst by taking activated carbon, zinc acetate [(CH3COO)2Zn.2H2O] and copper acetate (C4H6CuO4.H2O) as raw materials, mixing activated carbon, zinc acetate and copper acetate according to a mass ratio of (1-10): (1-2): (1-2), and roasting the obtained material for 60-150 minutes in an inert atmosphere according to a ratio of dried substance mass to microwave power of 1: (30-60) g/W at a roasting temperature of 400-800 DEG C to obtain the ZnO-Cu2O-AC photo catalyst. The ZnO-Cu2O-AC photo catalyst prepared by the preparation method disclosed by the invention can effectively degrade azo dyes such as methyl orange and the like, and has relatively good environmental protection benefits. 本发明涉及一种ZnO-Cu2O-AC光催化剂的制备方法及其应用，属于光催化技术领域。以活性炭、醋酸锌[(CH3COO)2Zn·2H2O]、醋酸铜(C4H6CuO4·H2O)为原料制备催化剂，将活性炭：醋酸锌：醋酸铜按照质量比为1~
