摘要 以Bi2O3和Mn Cl2·4H2O为原料,利用水解法合成了Mn/Bi OCl催化剂。用XRD、HRTEM等对其进行了表征。以苯酚作为光催化反应模型化合物,考察了Mn/Bi OCl催化剂的紫外光催化活性。并评价了清除剂对催化剂紫外光催化活性的影响。结果表明:Mn的含量对Mn/Bi OCl催化剂的光催化活性有很大影响。当n(Mn)∶n(Bi)为1∶100时,所合成的Mn/Bi OCl催化剂光催化活性最高,苯酚的光催化降解率达到70.3%。 Using Bi203 and MnCl2·4H2O as raw materials, Mn/BiOC1 photocatalysts have been prepared by the hydr- olysis method, and characterized by XRD, HRTEM, etc. By using phenol as a photocatalytic reaction model compound, the UV photocatalytic activity of Mn/BiOCI is investigated. The effects of scavengers on the ultraviolet photocatalytie activities are evaluated. The results show that the Mn content has important effect on the photocatalystic activity of Mn/BiOCl photoeatalyst. When n (Mn) :n (Bi) is 1:100, the photoeatalytic activity of the synthesized Mn/BiOCl pho- tocatalyst is the highest, and the photoeatalytie degradation rate of phenol reaches 70.3%.
