摘要

以CdCl

和Na

TeO

为反应物

抗坏血酸为还原剂

通过湿化学法合成CdTe量子点/膨润土复合材料。采用X射线衍射、荧光光谱及紫外-可见光谱等分析技术对其结构及光学性能进行表征。以汞灯为光源

甲基橙为目标污染物

研究了CdTe/膨润土复合材料的光催化活性。实验表明:在甲基橙溶液初始浓度为10 mg/L 时

经汞灯光照反应60 min后

CdTe/膨润土因光催化反应对甲基橙的降解率为66.23%

优于CdTe量子点光催化剂。

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.
