Abstract

g-C3N4/NiO photocatalysts were prepared by molten salt method and used melamine as precursor and ZnCl2/NiCl2 salt as reaction medium,respectively.The structure and properties of the photocatalysts were characterized by TEM,XRD and FT-IR.Using a xenon lamp as a light source and soluble dye RhB as the target degradation material,the photocatalytic degradation capability of g-C3N4/NiO was investigated.The results demonstrated that the formation of heterojunction between g-C3N4 and NiO resulted in the enhanced light absorption and efficient charge separation and transfer,thus improving photocatalytic activity.In addition,the photocatalytic degradation performance of g-C3N4/NiO was higher than that of g-C3N4,and g-C3N4/NiO(6) achieved the highest photocatalytic activity.
