METALLIC NANOPARTICLE CATALYSTS EMBEDDED IN POROUS OXIDE SUPPORT, WHICH SHOW HIGH CATALYTIC ACTIVITY EVEN AT LOW TEMPERATURES

Document Type and Number:

WIPO Patent Application WO/2020/197200

Kind Code:

A1

Abstract:

The present invention relates to a metallic nanoparticle catalyst and, more specifically, to a porous catalyst having metallic nanoparticles embedded in a porous oxide support and to a method for preparing the porous catalyst. To this end, a porous catalyst composition having metallic nanoparticles of the present invention comprises: an oxide matrix structure having mesopores and micropores; and metal or metal oxide nanoparticles embedded in the oxide matrix structure having mesopores and micropores. A method for preparing a porous catalyst composition having metallic nanoparticles of the present invention comprises the steps of: covering metallic nanoparticles containing at least any one of metals and metal oxides with a stabilizer to stabilize the metallic nanoparticles and then binding a polymer to the surface of the metallic nanoparticles to functionalize the metallic nanoparticles; mixing an oxide precursor in a solution in which the functionalized metal nanoparticles and an activator are mixed and dispersed, thereby synthesizing a metallic nanoparticle dispersion embedded in a porous oxide support; and firing the metallic nanoparticle dispersion. Thus, metallic nanoparticle catalysts having high activity even at low temperatures are realized.
