以Bi2O3和MnCl2·4H2O为原料，利用水解法合成了Mn/BiOCl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/BiOCl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/BiOCl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/BiOCl催化剂光催化活性最高，苯酚的光催化降解率达到70．3%。

Using Bi2O3 and MnCl2·4H2O as raw materials,Mn/BiOCl 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/BiOCl is investigated. The effects of scavengers on the ultraviolet photocatalytic activities are evaluated. The results show that the Mn content has important effect on the photocatalystic activity of Mn/BiOCl photocatalyst. When n(Mn)∶n(Bi) is 1∶100, the photocatalytic activity of the synthesized Mn/BiOCl pho-tocatalyst is the highest,and the photocatalytic degradation rate of phenol reaches 70.3%.
