| Abstract: | CNT/CdS composite films for response to visible light were prepared by co-precipitation process.The experiment of photocatalytic decolorization of methyl orange dye assisted by hydrogen peroxide was conducted under Xenon lamp simulated sunlight irradiation.Effects of different process,catalyst amount,H2O2 dosage,initial dye concentration,pH,different anions and reusability of catalyst on photocatalytic decolorization of methyl orange were studied.Results showed that H2O2 cooperated with CNT/CdS photocatalyt... |
