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/Cd S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/Cd S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/Cd S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/Cd S光催化降解甲基橙的降解率达84.7%。Using Cd （CH3COO）2· 2H2O, Mn （CH3COO）2·4H2O and Na2S· 9H2O as raw materials, Mn/CdS pnotocata- lysts 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 photocata- lytic reaction. The results show that the mass fraction of Mn^2＋ 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%.
