Title:
SINTERING-RESISTANT METAL CATALYST SUPPORTED ON SINGLE ATOMIC CE-DOPED METAL OXIDES, METHOD OF PREPARING SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/136591
Kind Code:
A1
Abstract:
The present invention relates to a sintering-resistant metal catalyst supported on a single atomic Ce-doped metal oxide and use thereof and, more specifically, to a sintering-resistant metal catalyst, a method for preparing same, and use thereof, wherein the metal catalyst has improved resistance to sintering while maintaining metallicity of a metal even in a high-temperature thermochemical reaction, by containing an active metal component in a metal oxide carrier doped with single atomic sized Ce. The metal catalyst has improved resistance to sintering while maintaining metallicity of the active metal, and thus exhibits excellent catalytic performance in a high-temperature thermochemical reaction, such as aromatization, dehydrogenation, or hydrogenation of hydrocarbons.
