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%。
以Cd（CH3COO）2·2H2O、Mn（CH3COO）2·4H2O及Na2S·9H2O為原料，採用共沉澱方法閤成瞭Mn/CdS光催化劑，併用XRD、HRTEM對其進行錶徵。以甲基橙為光催化反應的模型，攷察瞭Mn/CdS光催化劑的紫外光催化活性。實驗結果錶明：實驗樣品中Mn2+的質量分數對Mn/CdS光催化劑的紫外光催化活性有重要影響，噹w（Mn）為0.50%時Mn/CdS光催化降解甲基橙的降解率達84.7%。
이Cd（CH3COO）2·2H2O、Mn（CH3COO）2·4H2O급Na2S·9H2O위원료，채용공침정방법합성료Mn/CdS광최화제，병용XRD、HRTEM대기진행표정。이갑기등위광최화반응적모형，고찰료Mn/CdS광최화제적자외광최화활성。실험결과표명：실험양품중Mn2+적질량분수대Mn/CdS광최화제적자외광최화활성유중요영향，당w（Mn）위0.50%시Mn/CdS광최화강해갑기등적강해솔체84.7%。
Using Cd(CH3COO)2·2H2O,Mn(CH3COO)2·4H2O and Na2S·9H2O as raw materials,Mn/CdS photocata-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 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%.
