Abstract
The present disclosure provides a method for fabricating a nickel-cerium dioxide-aluminum oxide hybrid nanoparticle cluster catalyst. The method includes a solution preparation step, an aerosolizing step, a drying step, a first calcining step, a reducing gas adding step, and a second calcining step. The solution preparation step is provided for preparing a precursor solution. The aerosolizing step is performed for obtaining an atomized droplet. The drying step is performed for converting to a precursor crystallite. The first calcining step is performed for obtaining an oxidation state catalyst. The reducing gas adding step is performed for adding hydrogen. The second calcining step is performed for obtaining the nickel-cerium dioxide-aluminum oxide hybrid nanoparticle cluster catalyst.
