摘　　要：采用离子交换法制备了铜掺杂多孔氧化镍(Copper-doped NiO)非均相催化材料;通过扫描电子显微镜、X射线衍射、傅里叶变换红外光谱和热重分析对其形貌和结构进行了表征.结果表明,Copper-doped NiO呈均匀的片状花形结构分布,其晶体结构与NiO的晶体结构相同,Copper-doped Ni-MOF稳定性比Ni-MOF好.以苯甲醇催化氧化反应为探针反应,对Copper-doped NiO的催化性能进行测试,结果表明,苯甲醇的转化率高达99%,苯甲醛的选择性为99%,且该催化材料在循环5次后具有良好的循环稳定性.A copper-doped porous NiO heterogeneous catalyst was successfully fabricated by a metal-ion exchange method.The catalyst was characterized by SEM,XRD,FTIR,TGA.The SEM results showed that copper-doped NiO uniformly distributed with a flower-like structure;the XRD and FTIR results showed that the crystal structure of copper-doped NiO was the same as NiO;the TGA results showed that the stability of copper-doped NiO was better than that of Ni-MOF.The copper-doped NiO was evaluated as a catalyst for the aerobic oxidation of benzyl alcohol.99%conversion of benzyl alcohol and 99%selectivity of benzaldehyde were obtained,at the same time,the copper-doped NiO heterogeneous catalyst still has an excellent stability after 5 cycles.
