Heterogeneous catalyst with dual catalytic centers, and preparation method and use thereof

Abstract

A catalyst with dual catalytic centers, and a preparation method and use thereof, as well as a method for producing glycols are provided. The catalyst contains a porous support and C3N4, a hydrogenation metal and a retro-aldol catalytic metal loaded on the porous support. The hydrogenation metal and the retro-aldol catalytic metal form clusters with C3N4. The hydrogenation metal and the retro-aldol catalytic metal are loaded on the porous support by coordination with the N site, and form clusters with C3N4, effectively stabilizing the metal active sites. The catalyst is used for producing glycols from a polyhydroxy compound.
