Abstract

In this paper, five kinds of composite materials were prepared by using graphene oxide (or graphene) doped with TiO2. The photocatalytic properties of five kinds of composite materials, pure graphene oxide and pure TiO2 for methyl orange, phenol solution and rhodamine B simulated laboratory wastewater were studied respectively. The experimental results show that the photocatalytic performance of graphene oxide-doped titanium dioxide composites is better than that of graphene oxide-doped titanium dioxide composites. When graphene oxide is doped with titanium dioxide as catalyst, the higher the purity of graphene oxide, the better the photocatalytic effect of the composite material. Doped titanium dioxide is better than undoped titanium dioxide. When the amount of doped titanium dioxide is 0.3g, the photocatalytic effect is the best. Based on the comprehensive data, it can be clearly found that graphene oxide doped TiO2 composite is more suitable for degrading rhodamine system. By simulating the treatment of laboratory wastewater, it lays a theoretical foundation for the treatment of laboratory wastewater in the future.
