One-pot solvothermal preparation and enhanced photocatalytic activity of metallic silver and graphene co-doped BiVO4 ternary systems

- We have obtained Ag/GR/BiVO4 ternary system by one-pot solvothermal route.
- The best photocatalytic activity to RhB has been attained for 3%Ag/5%GR/BiVO4.
- Silver nanoparticles and graphene nanosheets doping clearly favor the photocarriers separation.
- The Ag/GR/BiVO4 heterojunction photocatalyst can be reused five times without obvious loss of the reactivity.
