METHOD FOR PREPARING ORGANIC SOLVENT-ACTIVATED NANO MAGNESIUM POWDER

WIPO Patent Application WO/2024/021213

A1

A method for preparing an organic solvent-activated nano magnesium powder, which method belongs to the technical fields of nano material preparation, hydrogen storage materials and hydrogen storage application. The method for preparing an organic solvent-activated nano magnesium powder comprises the following steps: reacting a mixture containing a magnesium source and an organic solvent to obtain an activated nano magnesium powder, wherein the mass ratio of the magnesium source to the organic solvent is 1 : 0.1 to 1 : 1. By means of the method, the magnesium powder is significantly reduced from millimeter scale to micron scale or even nanoscale, and the chemical adsorption of the organic solvent on the surface of the magnesium powder greatly improves the surface activity; the prepared nano magnesium powder can significantly absorb hydrogen at room temperature, and can be quickly hydrogenated into magnesium hydride with high economic value under mild conditions; and the method has a simple and feasible process and is suitable for large-scale amplified production.
