Title:

EMBEDDED HYDROTHERMAL-RESISTANT NISN-CS NANOCATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2023/024254

Kind Code:

A1

Abstract:

Disclosed in the present invention are an embedded hydrothermal-resistant NiSn-CS nanocatalyst, a preparation method therefor and an application thereof. The method comprises the following steps: first dissolving Ni salt, Sn salt and chitosan to form a sol solution, then removing a solvent in the sol solution to obtain a gel, and carbonizing the gel to obtain the embedded hydrothermal-resistant NiSn-CS nanocatalyst, wherein the carbonization temperature is 400°C-600°C, and the carbonization time is 1-4 h. The embedded hydrothermal-resistant NiSn-CS nanocatalyst prepared by the present invention significantly improves the dispersity of the NiSn catalytic active center and the stability of the structure and activity of the NiSn catalytic active center in a hydrothermal environment, and exhibits excellent catalytic efficiency and hydrothermal-resistant stability when applied to micromolecular alcohol synthesis of high-carbon alcohol, is easy to separate and recover, has small pollution, and has excellent cyclic utilization.
