Abstract

CdTe/bentonite composites were successfully prepared by using CdCl

and Na

TeO

as reactants and ascorbic acid as reducing agent. The obtained samples were characterized by X-ray diffraction (XRD)

fluorescence spectrophotometer and ultraviolet-visible spectra (UV-Vis). The effect of CdTe/bentonite composites on photocatalysis degradation of methyl orange was investigated in detail. Under irradiation by mercury lamp for 60 min

it was found that 66.23% of degradation rate was achieved when the dye initial concentration was 10 mg/L. The experiment results show that the performance of CdTe/bentonite composites catalyst is superior to pure CdTe quantum dots.
