SYNTHESIS OF TRIMETALLIC NANOPARTICLES BY HOMOGENEOUS DEPOSITION PRECIPITATION, AND APPLICATION OF THE SUPPORTED CATALYST FOR CARBON DIOXIDE REFORMING OF METHANE

摘要

Disclosed is a supported nanoparticle catalyst, methods of making the supported nanoparticle 5 catalysts and uses thereof. The supported nanoparticle catalyst includes catalytic metals M1, M2, M3, and a support material. M1 and M2 are different and are each selected from nickel (Ni), cobalt (Co), manganese (Mn), iron (Fe), copper (Cu) or zinc (Zn), wherein M1 and M2 are dispersed in the support material. M3 is a noble metal deposited on the surface of the nanoparticle catalyst and/or dispersed in the support material. The nanoparticle catalyst is 10 capable of producing hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2).
