The present disclosure provides a method for fabricating a heterogeneous nickel-based catalyst on aluminum oxide support. The method includes a solution preparation step, a drop-cast step, a first calcining step, and a second calcining step. The solution preparation step is provided for preparing a precursor solution. The drop-cast step is provided for dropping the precursor on the support. The first calcining step is provided for obtaining an oxidation state catalyst. The second calcining step is provided for obtaining the heterogeneous nickel-based catalysts on aluminum oxide support. Accordingly, the present disclosure can control the condition of the heterogeneous nickel-based catalysts on aluminum oxide support to achieve high activity and good operation stability. The heterogeneous nickel-based catalysts on aluminum oxide support can be used to catalyze reductive amination of propylene glycol to synthesize the polyetheramine.
