BiVO4@MoS2 core-shell heterojunction with improved photocatalytic activity for discoloration of Rhodamine B

Abstract Heterojunction photocatalysts can accelerate photo-excited electron-hole separation in the photocatalytic application. Herein, one BiVO4@MoS2 core-shell heterojunction was synthesized via growing MoS2 nanosheets on electrospinning-fabricated BiVO4 nanorods by solvothermal technique. The MoS2/BiVO4 heterojunction can completely degrade RhB solution within 20 min without any additional agent. According to the S-scheme heterojunction principle, the electron transfer process retains the powerful electrons in CB of MoS2 and powerful holes in VB of BiVO4, and then promotes the excellent redox ability and strong driving force for photocatalytic discoloration of RhB.
