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.
