Nickel-based catalyst for catalytic combustion of VOCs gas and preparation method of nickel-based catalyst

The invention discloses a nickel-based catalyst for VOCs gas catalytic combustion and a preparation method thereof. The preparation method comprises the following steps: by taking foamed nickel as a carrier, loading Co, Ce and Ni through MOF, and preparing a CoCe foamed nickel catalyst from the MOF loaded with catalyst active components and the foamed nickel coated with aluminum sol; the porous foamed nickel serves as a carrier, agglomeration of active components of the catalyst is reduced, an MOF precursor is formed through the active components and loaded on the foamed nickel, and uniform dispersion of the active components of the catalyst is achieved through the combined action of the porous foamed nickel and MOF; meanwhile, the metal components Co, Ce and Ni are matched with one another, especially the MOF structure of Ni and the co-metal synergistic effect of foamed nickel, so that the catalytic activity of Co and Ce can be greatly improved, the cost of the catalyst is reduced, a good catalytic effect ca
