Abstract：CuO/graphene is in- situ prepared by the co- precipitation method using Cu(NO3)2·3H2O and graphene oxide as raw materials. The catalyst is characterized by XRD and SEM. The catalytic performance is investigated by degradating methylene blue solution under the ultraviolet light and applied electric field. The results show that graphene has enhanced the adsorption and electrical conductivity of the catalyst and the applied electric field makes a three electrode system between catalyst particles and the two electrode plates. The catalytic properties of CuO have been highly improved because of the introduction of graphene and applied electric field. Compared with pure CuO, the photocatalytic degradation of methylene blue by CuO/graphene increases from 33.23% to 91.77%, and the photo- electro catalytic degradation of methylene blue reaches 93.16%.
