Abstract:
In order to increase the rate of Cu2ZnSnS4 （CZTS） photocatalytic degradation of Rhodamine B （RhB）， type-Ⅰ heterojunction of the CZTS/g-C3N4 composite structure was successfully prepared by a hydrothermal method in this work. CZTS/g-C3N4 is applied in photocatalytic degradation of the colored dye RhB. The results showed that g-C3N4 was attached to the surface of flower-like CZTS， and the two formed a type-Ⅰ heterojunction. CZTS acted as an electron trap for g-C3N4， which improved the separation efficiency of carriers. The results of photocatalytic degradation of RhB showed that CZTS/g-C3N4 composite structure could improve the photocatalytic degradation effect of RhB. The best photocatalytic efficiency of RhB was 98.63% within 60 min.
