摘　　要：以H_2C_2O_4和CuSO_4通过沉淀法制备了草酸铜,并对所制备的化合物进行了X射线粉末衍射(XRD)、扫描电镜(SEM)和X射线光电子能谱(XPS)的表征.结果表明,制备草酸铜为斜方晶系的草酸铜.以制备的草酸铜为催化剂,研究了其对苯直接氧化制备苯酚的催化性能,并考察了催化剂量、H_2O_2量、反应时间等反应条件对该反应的影响.结果表明,在优化条件下,草酸铜催化剂可以催化双氧水氧化苯得到13.1%苯酚,并且该催化剂可以重复使用,回收率高.Copper oxalate was prepared by the precipitation method with H2C20 4 and CuS0 4. The prepared copper oxalate was characterized by XRD,SEM and XPS. It revealed that pre-pared compound was the copper oxalate and was in the orthorhombic system. Its catalytic performance was investigated by the reaction of direct hydroxylation of benzene to phenol.The reaction conditions,which included the dosage of catalyst,the amount of H2〇2 ？the reac-tion time, were optimized. Under the optimal condition, the yield of phenol was 13. 1 % . Furthermore, the catalyst could be reused with the high recovery.
