Electroless Co-Ni-P thin film as-deposited was amorphous possessing smooth surface. The film was crystallized after heat treatment at 300℃ for 1 hour, and the surface of film was composed of "taper humps". When the film was heated, phase of Co2P deposited from the solid solution and allotropic transformation took place from hexagonal close-packed system to face-centred cubic lattice.

Comparing with the activity of NiO/γ-Al_2O_3, NiO/TiO_2, and NiO/CeO_2catalysts, NiO/CeO_2 showed the highest light-off conversions of NO and CO and lowesttemperature of total conversion. Three kind of CeO_2 prepared by homogeneousprecipitation, precipitation, and direct decomposition method wereused as the carrier of NiO. Through the activity comparison of NiO/CeO_2, NiO/CeO_2and NiO/CeO_2, CeO_2 optimized as the preferable carrier for active component at aspace velocity of 120 000h~(-1, the coversion of NO is 50％at 170℃over NiO/CeO_2catalyst, and the complete conversion of NO and CO occurred at 210℃.
