Effect of the Nickel Source on the Structure, Performance, and Carbon Deposition of the Ni/AlO Catalyst for CO-CH Reforming.

Ni/AlO catalysts were prepared with Ni(NO)·6HO, NiSO·6HO, NiCl·6HO, and NiCHO·4HO as nickel sources by the solution combustion method. The catalysts were characterized by X-ray diffraction, H temperature-programmed hydrogenation, TG-DTG, TPH, and transmission electron microscopy methods, and the effect of the nickel source on performance of the Ni/AlO catalyst was investigated via the CO-CH reforming experiment. Results showed that Ni dispersion, Ni size, and the metal-support interaction between active component Ni and the support were influenced significantly by anion in nickel sources, resulting in that the performance of each catalyst was different.
