摘　　要：分别以硝酸铜、氯化铜、硫酸铜为原料,通过溶胶-凝胶法制备尖晶石型CuAl_2O_4粉体,采用X射线衍射仪、光催化反应器、红外光谱仪、X射线光电子能谱仪等研究了粉体的物相组成、光催化性能和微观结构。结果表明:以硫酸铜为原料,在焙烧温度为700℃,氨水体积20mL条件下合成的CuAl_2O_4粉体的光催化性能最佳,对甲基橙的降解率达到90%;以硫酸铜为原料制备的CuAl_2O_4粉体中存在Cu_2O(SO_4)相,提高了CuAl_2O_4粉体的光催化性能。Spinel-type CuAl2O4 powder was prepared by sol-gel method with copper nitrate,copper chloride,and copper sulfate as raw materials,respectively.The phase composition, photocatalytic property and microstructure of the powder were studied by X-ray diffractometer,photocatalytic reactor,infrared spectroscope and X-ray photoelectron spectrometer.The results show that the CuAl2O4 powder,prepared at 700 ℃ with copper sulfate raw material added with 20 mL ammonia,had the best photocatalytic property,and the degradation rate of methyl orange was 90%.There was Cu2O（SO4）phase in the CuAl2O4 powder prepared with raw material of copper sulfate.The Cu2O（SO4）phase improved the photocatalytic property of CuAl2O4 powder.
