Abstract

See full text

The present invention relates to a catalyst composition comprising a gold nanoparticle superlattice embedded in hierarchical porous silica and a method for manufacturing the same. The catalyst composition comprising a gold nanoparticle superlattice embedded in hierarchical porous silica according to the present invention comprises micropores and mesopores in the superlattice, so that these pores are channelized to allow the rapid access of reactants to surfaces of gold nanoparticles, and the catalyst composition is very structurally stable and has excellent catalytic activity, and thus has an effect of exhibiting a CO conversion rate of 100% at room temperature.
