Mesoporous Ce0.8Zr0.2O2 oxides were prepared by a surfactant-assisted method of nanocrystalline particle assembly, and used as a support of nickel oxide nanocatalysts. The obtained mesoporous NiO/Ce0.8Zr0.2O2 nanocatalysts were characterized by XRD, N2 adsorption, TEM, H2-TPR and X-ray photoelectron spectroscopy techniques. The catalytic properties of the NiO/Ce0.8Zr0.2O2 nanocatalysts were evaluated by CO oxidation and toluene combustion. The results showed that the catalyst with 10 wt% NiO loading exhibited the highest catalytic activity for CO oxidation and toluene combustion.
