Abstract

Abstract: Photocatalysts with heterojunction structure have been widely used for organic degradation. In this study, CuS/g-C3 N4 heterojunction was formed by in situ self-assembly via a simply hydrothermal method. A series of characterizations were applied to analyzing the morphology, structure, optical properties and photo-induced electron transfer of the samples. The effect of CuS mass ratio in the CuS/g-C3 N4 composite on methyl blue (10 mg l −1 ) degradation under visible-light illumination was discussed. When CuS mass ratio was 60%, CuS/g-C3 N4 behaved the highest photocatalytic efficiency which is 17 times higher than that of pure g-C3 N4, and the optimal heterojunction exhibited promising photocatalytic stability as well. The synthesized CuS/g-C3 N4 with intimate contact and promising photocatalytic performance provides important implications on analogous researches on g-C3 N4 -based heterojunctions for photocatalytic applications.
