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.

Abstract:

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.

Key words: Porous NiO, Copper, Heterogeneous catalyst, Benzyl alcohol, Aerobic oxidation
