FIELD: chemistry.

SUBSTANCE: nickel-copper oxide catalysts on metal carrier can be used in conversion of CO into CO₂ in high-temperature processes of technological and exhaust gas purification, in particular, in energy and automobile industry. Catalysts on carrier, made from aluminium or its alloy are obtained by plasma-electrochemical method by means of carrier processing in alkali electrolyte, containing nickel acetate and copper acetate and additionally including trisodium phosphate, sodium tetraborate and tungstate with following ratio of components, g/l: nickel acetate Ni(CH₃COO)₂·4H₂O-5-20; copper acetate Cu(CH₃COO)₂·H₂O-1.3-5.0; trisodium phosphate Na₃PO₄·12H₂O-20-30; sodium tetraborate Na₂B₄O₇·10H₂O-10-20; sodium tungstate Na₂WO₄·2H₂O-1-3. Plasma-electrochemical processing is carried out in galvano-static mode by pulse current, alternating or alternating unidirectional, with impulse duration 0.0033-0.04 sec, voltage 240-400 V, efficient current density 5-20 A/dm² and electricity amount consumption 1500-6000 C/dm² of formed catalytically active layer. Obtained catalyst is stable in temperature range 300-500° and ensures degree of CO into CO₂ conversion in wide limits (from 37 to 97%).

EFFECT: increased catalyst stability.
