The present disclosure provides a method for fabricating a catalyst. The method includes a solution preparation step, an aerosolization step, a drying step, a first calcining step, a reducing gas addition step and a second calcining step. The solution preparation step is provided for obtaining a precursor solution. The aerosolization step is provided for obtaining an aerosolized droplet. The drying step is provided to self-assemble the aerosolized droplet into a catalyst oxidation precursor. The first calcining step is provided for obtaining an oxidation state catalyst. The second calcining step is provided for obtaining the reduction state catalyst. Accordingly, the present disclosure can control the oxidation state of the sample, improve the catalytic activity, stability and selectivity of the catalyst for effectively applying to the catalytic reaction of methane combustion, as well as effectively reutilizing CO2and methane.
