Preparation of ZnxCd1-xS solid solution and its performance of photodegradation of methylene blue
In this paper,ZnxCd1-xS solid solution material was successfully prepared by hydrothermal method,and its photocatalytic performance was investigated by photocatalytic degradation of methylene blue(MB).The photocatalytic experiment results showed that the removal efficiency of Zn0.2Cd0.8S solid solution material reached 81.94％,close to 1.43 times of pure CdS and 1.47 times of ZnS.The possible reasons for the enhancement of photocatalytic performance were explored through characterization such as XRD,UV vis diffuse reflectance absorption spectroscopy,and EIS.The results show that the Zn0.2Cd0.8S solid solution material has a high carrier separation efficiency,and a strong light absorption ability in the visible light region,thus enhancing the photocatalytic performance.
