FIELD: chemistry.
SUBSTANCE: invention relates to catalysts. Described is a method of activating metal oxide catalysts for synthesis of carbon nanomaterials, involving use of magnesium nitrate and group VIII metal salts as starting material which is treated via thermal decomposition, which involves calcination of an aqueous solution of precursors which, before calcination, is exposed to ultrasound at frequency 22 kHz and intensity 50-100 W/cm2 for 5-60 s, after which the solution is heated to temperature 600°C for 30 minutes.
EFFECT: activation method increases output of carbon nanomaterials.
