Abstract
Photocatalysis, as one of the most advanced oxidation techniques, has been paid more and more attention due to its advantages in solving environmental pollution problems, such as low cost, eco-friendly, efficiently and no secondary pollution. In this paper, we fabricated a series of Ce doped CoIn2S4 photocatalyst with different Ce content via solvothermal reaction and explored the influence of Ce on the photocatalytic activity of CoIn2S4. The properties of all samples were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), ultraviolet spectrophotometer (UV–vis), transmission electron microscope (TEM) and so on. The results show that the do** of Ce can highly improve the photocatalytic activity of CoIn2S4. When CoIn2S4 is doped with 0.1 g of Ce(NO3)3·6H2O, it exhibits the highest photocatalytic activity and can degrade 98.55% of rhodamine B (RhB). This strategy of do** rare earth element on semiconductor provides a facile and promising way to the remediation of environmental pollution.
