To improve the water dispersibility of graphene based powder photocatalyst, titanium dioxide / graphene (TG) was first prepared using a hydrothermal method in this paper, and then the ternary composite photocatalytic materials were prepared by covalently grafting TG with dyes containing hydrophilic groups. The bandgap, water dispersibility, and photocatalytic degradation performance of methylene blue (MB) simulated wastewater of the photo-catalysts were mainly investigated. The results showed that the bandgaps of the DTG series of composites were narrowed compared to that of TG, extending the light response range to the visible light region. The composite D2.70 TG exhibited good water dispersibility, and no significant precipitation aggregation occurred after 7 days of testing. The removal rate of MB in the simulated wastewater by D2.70 TG under the irradiation of visible light for 2 h was over 99%, and the removal rate remained above 95% after 5 cycles of experimentation.
