  • Patent number: 11141715
    Abstract: The present disclosure provides a method for fabricating a heterogeneous nickel-based catalyst on an 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.

  • Publication number: 20210154655
    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.
