摘要/Abstract

摘要：

以Cd(CH₃COO)₂·2H₂O、Mn(CH₃COO)₂·4H₂O及Na₂S·9H₂O为原料,采用共沉淀方法合成了Mn/CdS光催化剂,并用XRD、HRTEM对其进行表征。以甲基橙为光催化反应的模型,考察了Mn/CdS光催化剂的紫外光催化活性。实验结果表明:实验样品中Mn²⁺的质量分数对Mn/CdS光催化剂的紫外光催化活性有重要影响,当w(Mn)为0.50%时Mn/CdS光催化降解甲基橙的降解率达84.7%。

Abstract:

Using Cd(CH₃COO)₂·2H₂O,Mn(CH₃COO)₂·4H₂O and Na₂S·9H₂O as raw materials,Mn/CdS photocatalysts have been synthesized by a co-precipitated method,and characterized by XRD and HRTEM. The ultraviolet photocatalytic activity of Mn/CdS photocatalyst is investigated with methyl orange as model compounds of photocatalytic reaction. The results show that the mass fraction of Mn²⁺ in the samples has important influence on the ultraviolet photocatalytic activity of the Mn/CdS photocatalyst. When w(Mn) is 0.50%,photocatalytic degradation rate of methyl orange by using Mn/CdS as photocatalyst reaches 84.7%.

Key words: Mn-doped, cadmium sulfide, photocatalyst, methyl orange
