Ni-based catalyst prepared through solution combustion and method thereof

The invention relates to the technical field of a Ni-based catalyst, in particular to a Ni-based catalyst prepared through solution combustion and a preparation method thereof. The Ni-based catalyst is prepared from the following method including the steps of taking a certain amount of nickel nitrate hexahydrate or nickel acetate or nickel chloride and aluminum nitrate nonahydrate or aluminum acetate or aluminum chloride; using polypyrrolidone as a morphological regulating and controlling agent; adding a deionized water and ethylene glycol mixed solution; performing ultrasound processing to obtain a precursor test solution; raising the temperature through a muffle furnace program; burning the test solution in the muffle furnace; preparing a combustion body test specimen; then, performing cooing, grinding and sieving; performing high-temperature reduction by H2 to obtain the Ni-based catalyst prepared through solution combustion. The method belongs to a method for simply and fast preparing the Ni-based catalys
