摘要
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.关键词
