Abstract

Using g-C3N4 as the main catalyst,α-Fe2O3 as the catalyst and RGO as the electron channel,the g-C3N4/α-Fe2O3/RGO ternary photocatalyst was constructed by high-temperature calcining,hydrothermal and mechanical stirring methods.The photocatalytic degradation of rhodamine B by photocatalyst with different RGO contents under visible light was investigated,and the structure and morphology of the catalyst were characterized.The results shown that the hexagonal columnar α-Fe2O3 was loaded on the lamellar g-C3N4,surrounded by floccus RGO.Degradation experiments showed that the catalytic activity of g-C3N4/α-Fe2O3/RGO was better than that of g-C3N4/α-Fe2O3.When the content of RGO was 5%,the photocatalytic performance of g-C3N4/α-Fe2O3/RGO was the best.This was mainly due to the addition of α-Fe2O3 to broaden the optical response range of the material,in addition,the addition of RGO provided an electronic channel,promoting the migration and separation of photogenerated electron-holes in the material.

Key words： g-C3N4; RGO; photocatalysis; RhB
