Document Type and Number:
WIPO Patent Application WO/2021/066521
Kind Code:
A1
Abstract:
The composite according to the present invention comprises: a mesoporous inorganic support having vacancy defects; and metal alloy nanoparticles dispersed in and bound to the mesoporous inorganic support and containing a precious metal element and an earth rare element. The composite according to the present invention has a very high specific surface area since the alloy is dispersed and present in the form of ultrafine nanoparticles in the porous support, and thus can show remarkably improved activity when used as a material for a chemical reaction, including a catalyst.
