FIELD: technological processes.
SUBSTANCE: invention relates to a method of producing copper-containing nano-catalysts with developed surface, which involves, that first from an electrolyte solution onto a metal carrier by electrodeposition copper is applied, then the carrier with the applied active metal is subjected to thermal processing. Electrodeposition process is performed in such a way, for to grow on a metal substrate with a heat conductivity coefficient less than 20 W/(m⋅K) a monolayer of icosahedral small particles of copper with micron sizes from 5 to 15 mcm and having 6 axes of symmetry of the 5th order, or layers of microcrystals with disclination type defects in the crystal lattice, then they are annealed in air atmosphere at the temperature of 300–400 °C and maintained for 4 hours till the small particles form a developed surface in the form of nanowhiskers or at the temperatures of 500–600 °C and maintained for 2–3 hours till the small particles form a developed surface in the form of nanopores, or inner cavities, or a corrugated relief.
EFFECT: technical result is producing a nano-catalyst with high specific surface, good adhesion to a carrier, high mechanical strength and low hydrodynamic resistance.
