Abstract
Catalysts that are resistant to high-temperature sintering and methods for preparing such catalysts that are resistant to sintering at high temperatures are provided. The catalysts include a metal nanoparticle bound to a metal oxide support, where the metal nanoparticle and support are coated with a porous metal oxide coating layer. The catalyst is prepared by contacting a metal nanoparticle bound to a metal oxide support with a solution of metal salts, drying the solution of metal salts, and calcining the metal salts to generate a porous metal oxide coating on the metal nanoparticle and metal oxide support.
