Summary: | The invention relates to the technical field of preparation of sub-nano materials and in particular to a method for preparing a full-hydrolysis catalyst with nickel monatomic double active sites. Themethod comprises the following steps: by taking nickel acetylacetone and a metal organic framework structure as raw materials, and ethanol as a solvent, performing dissolution, stirring, mixing, cleaning and vacuum drying so as to obtain ZIF-67; dissolving the ZIF-67 and the nickel acetylacetone into the ethanol, performing ultrasonic dispersion, and performing stirring till the materials are completely dried; and introducing argon, increasing the temperature to 700-750 DEG C, keeping the temperature for 2-3 hours, and performing natural furnace cooling, so as to obtain the full-hydrolysis catalyst with nickel monatomic double active sites. The method has the advantages of being low in cost, rapid in reaction velocity, mild in reaction, easy in reaction control, energy-saving and environment-friendly, high in prod |
