METHOD OF PREPARING NANOSIZED CATALYST FOR PRODUCING CARBON NANOMATERIALS AND HYDROGEN Russian patent published in 2025 - IPC B01J37/08 B01J35/45 B01J21/02 B01J23/755 

FIELD: chemical industry.

SUBSTANCE: invention relates to preparation of catalysts used in chemical industry, and can be used in the technology of processing various hydrocarbon gases (for example, C_nH_2n+2, where n>1) and/or mixtures thereof in various combinations, used in the technology of producing carbon nanomaterials and hydrogen. Disclosed is a method of preparing a nanosized catalyst for producing carbon nanomaterials and hydrogen, which consists in dissolving catalyst initial components in distilled water, in form of crystalline hydrates of nickel and aluminum metals, exhibiting oxidative properties, and organic fuel, selected from urotropin, glycine, urea, starch, sucrose, citric, tartaric or oxalic acids, having reducing properties, as a result of thermal treatment of obtained solution in a muffle furnace at a rate of temperature increase in furnace of 1–15 °C/min from room temperature to temperature of 350–450 °C, accompanied by a process of evaporating water molecules to a gel-like state with initiation of a self-sustaining fuel combustion reaction, wherein thermal decomposition of crystalline hydrates of nickel and aluminum metals and organic fuel selected from urotropin, glycine, urea, starch, sucrose, citric, tartaric or oxalic acids is carried out under the effect of microwave radiation with microwave frequency of 2,450 MHz with rated power of not less than 800 W, accompanied by stages of dissolution of initial components of catalyst in own crystallization water, evaporation of the obtained complex solution to a gel-like state and initiation of combustion of the solution to form a nanosized catalyst.

EFFECT: considerable reduction of catalyst preparation time.
