Method for fabricating heterogeneous nickel-based catalyst on aluminum oxide support, heterogeneous nickel-based catalyst on aluminum oxide support and method for synthesizing polyetheramine

A method for fabricating a heterogeneous nickel-based catalyst on an aluminum oxide support, comprising:

• performing a solution preparation step, wherein a catalytically active precursor is used as a precursor solution, the precursor solution contains a nickel ion and a cerium ion, and a concentration of the nickel ion is 15 wt %, a concentration of the cerium ion is in a range of from greater than 5.0 wt % to 15 wt %;
• performing a drop-cast step, wherein the precursor solution is dropped on a support so as to obtain a catalyst precursor, and the support is an aluminum oxide support;
• performing a first calcining step, wherein the catalyst precursor is calcined so as to obtain an oxidation state catalyst;
• and
• performing a second calcining step, wherein the oxidation state catalyst is calcined under a reducing gas so as to obtain the heterogeneous nickel-based catalyst on the aluminum oxide support, the reducing gas is hydrogen, and a temperature of the second calcining step is 400° C.
