Title:
METALLIC NANO-CATALYST HAVING SEMI-COATED STRUCTURE, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/077609
Kind Code:
A1
Abstract:
A metallic nano-catalyst having a semi-coated structure, a preparation method therefor and an application thereof. The semi-coated metallic nano-catalyst comprises metal nanoparticles, and a coating material attached to part of the surface of the metal nanoparticles. The semi-coating structure of the semi-coated metallic nano-catalyst is in a single-coating state, where almost each metallic nano-particle is partly exposed to the outside and partly coated by the coating material. The metallic nano-catalyst having the semi-coated structure can catalyze both liquid-phase reaction and gas-phase reaction, can catalyze both high-temperature reaction and low-temperature reaction, has excellent thermal stability, produces good catalytic result, and has potential application value. Experimental results show that the metallic nano-catalyst having the semi-coated structure has high catalytic efficiency in high-temperature reaction at 400 to 600 °C.
