Recent studies have shown that the composite of semiconductor photocatalytic materials and g-C3N4 can effectively inhibit carrier recombination enhance adsorption performance materials, so photocatalyst has stronger activity. In this paper, three kinds graphitic carbon nitride with different morphologies were prepared using same precursor system by chemical cracking method. After characterization application, sample most significant activity was selected g-C3N4/BiVO4 heterostructure synthesized simple solvent evaporation method, then experiment carried out. The results show that, when content BiVO4 in is 1%, RhB highest, degradation rate could reach 90.4%. kinetic showed consistent quasi-primary model. cycle remains unchanged stable after four cycles. existence a binary heterojunction confirmed UV/Visible diffuse reflection (UV-DRS) photoluminescence (PL) experiments. Owing to Z-type charge process between g-C3N4, efficient separation achieved, thus enhancing capacity. This work provides new idea for study based on g-C3N4.
