Study on Preparation and Photocatalytic Performance of CdS-TiO_2 Photocatalyst AITranslate
Abstract AITranslate
TiO2and CdS-TiO2 photocatalysts were prepared with sol-gel method,and they were characterized by X-ray diffraction（XRD）,scanning electron microscope（SEM）and UV-Vis absorption spectroscopy.The results indicate that TiO2 is anatase and CdS is hexagonal after 500℃ vacuum treatment.CdS-TiO2 has the smallest particles with CdS doping amount of 5% molar fraction.Cd and S atomic ratio approaches1∶1.And CdS doping results in red shift of the absorption edge of TiO2.With the increase of doping amount of CdS,photocurrent of CdS-TiO2 is enhanced firstly and then weakened,and 5% CdS-TiO2 has the highest photocurrent of 1.2mA/cm^2.The results of degradation experiments of methylene blue in visible light show that with the increase of CdS doping amount,the degradation rate of methylene blue increases gradually by CdS-TiO2.The highest degradation rate of methylene blue is 57%,which is attributed to5% CdS-TiO2.
