1. A method for fabricating a nickel-cerium dioxide-aluminum oxide hybrid nanoparticle cluster catalyst, comprising:
performing a solution preparation step, wherein a catalytically active precursor and a supporter precursor are mixed to obtain a precursor solution, the catalytically active precursor contains a nickel ion and a cerium ion, the supporter precursor contains an aluminum ion, and pH value of the precursor solution is 2.5 to 4;
performing an aerosolizing step, wherein the precursor solution is aerosolized to obtain an atomized droplet;
performing a drying step, wherein the atomized droplet is converted to a precursor crystallite by evaporation-induced self-assembly;
performing a first calcining step, wherein the precursor crystallite is calcined to obtain an oxidation state catalyst;
performing a reducing gas adding step, wherein hydrogen is added as a reducing gas; and
performing a second calcining step, wherein the oxidation state catalyst is calcined to obtain the nickel-cerium dioxide-aluminum oxide hybrid nanoparticle cluster catalyst.
