A Novel Rose‐Like CuS/Bi2WO6 Composite for Rhodamine B Degradation

A novel rose‐like CuS/Bi2WO6 composite was successfully synthesized by a facile hydrothermal method for the first time. CuS/Bi2WO6 with different molar ratios was characterized by XRD, SEM, TEM, XPS, EIS and M−S. The morphology of samples has changed from sheet structure to ordered rose‐like shapes after the addition of CuS. The morphology difference indicated that the content of CuS has a certain effect on morphology. Experimental results show that the addition of CuS effectively improves the photocatalytic effect of Bi2WO6 due to the change of morphology. BWO‐3(the molar ratio of CuS and Bi2WO6 is 1:5) has the best photocatalytic performance, the degradation efficiency of Rhodamine B reaches 96.2% after 15 minutes. A novel rose‐like CuS/Bi2WO6 composite was successfully synthesized by a facile hydrothermal method for the first time. The morphology of samples has changed from nanosheets (BWO‐0) to ordered rose‐like shapes (BWO‐3) after the addition of CuS. The morphology difference indicated that the content of CuS has a certain effect on morphology.
