摘　　要：利用水热法通过调节溶液的pH值制备了{001}晶面和{010}晶面的BiOCl。利用XRD、Raman、DRS及BET等对其结构及性能进行了表征,通过双酚A(BPA)降解及CO_2还原实验考察了样品的光催化性能。研究表明,BiOCl{010}面催化剂的BPA降解速率及产生甲酸甲脂(MF)的速率分别是BiOCl{001}面催化剂的1.75倍、1.2倍。BiOCl{010}具有较高光催化活性的原因在于BiOCl{010}具有较大的比表面积和开放的孔道特性。BiOCl with {001} facets and {010} facets were prepared by hydrothermal method by adjusting the pH value of the solution. The structure and properties of the samples were characterized by XRD,Raman,DRS and BET. The photocatalytic properties of the samples were investigated by using BPA as a probe and CO2 reduction. The results show that the degradation rate and methyl formate（MF）generation rate of BiOCl {010} facets exceed that of BiOCl {001} facets catalysts by a factor of 1. 75 and 1. 20,respectively,owing to the larger specific surface area and open channel characteristic of the {010}surface catalyst.
