SUPPORTED CATALYST HAVING ACTIVE METAL ATOMICALLY DISPERSED IN SUPPORT, AND PREPARATION METHOD THEREFOR AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2020/252774

Kind Code:

A1

Abstract:

Disclosed is a supported catalyst having an active metal atomically dispersed in a support, comprising an active metal species and a metal oxide support, wherein the active metal comprises one or more of Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Rh, Pd, Ag, W, Ir, Pt, and Au, and the metal in the support comprises one or more of Ti, Zr, Nb, Ce, Al, Ga, In, Si, Ge, and Sn. Also disclosed are a preparation method for said catalyst and a use thereof. The supported catalyst having an active metal atomically dispersed in a support is prepared in the present invention by means of in-situ generation in the support, wherein no aggregated particles of the active metal species have a particle size of greater than 1 nm. The preparation method uses inexpensive raw materials, involves simple reaction operations, has a high-level of safety, requires no post-treatment steps, and is scalable for industrial production. In addition, the present invention has wide applications and can be used to further scientific research and expand production with regard to different catalysis systems.
