Synthesis of Spherical CuS Photocatalyst and the Research on Photo-Degradation Activity of Methylene Blue

Abstract

The CuS semiconductor photocatalysts with the spherical morphology have been synthesized through the solvothermal method. The as-prepared photocatalysts have been characterized by scanning electron microscopy (SEM), UV-vis absorption (UV-vis). The photo-degradation experiments of the the as-prepared photocatalysts were performed in the visible light illumination and the methylene blue was choose as the wastewater pollutants. Particularly, the CuS semiconductor photocatalysts shows the highest degradation ratio (70%) of methylene blue under the visible light irradiation.
