FIELD: chemistry.

SUBSTANCE: method includes processing, preparation and soaking of a carrier with an intermediate coating with an active phase salt solution. The carrier is prepared from reticulated foam polyurethane by soaking with ceramic slip, which contains an inert filler - electro-fused corundum, dispersive powder of aluminium oxide with additives of magnesium and titanium oxides and a solution of polyvinyl alcohol (PVA), dried at a temperature of 100…120°C, and annealed at a temperature of 1470…1510°C. Then the obtained ceramic highly-porous block-cellular matrix is successively soaked with an alumina sol solution in a quantity to 10.0 wt % of the carrier weight, dried at a temperature of 100…120°C and annealed in air at a temperature of 550…600°C, cooled, processed with a palladium chloride solution with the content of palladium of 1.5…4.0 g/l, dried at a temperature not higher than 120°C, annealed at a temperature of 450…500°C in air, reduced in a molecular hydrogen flow until a catalytic layer in the form of metal palladium with the weight content not higher than 1.0 wt % is formed at a temperature of 60…85°C.

EFFECT: method makes it possible to obtain catalysts, which have high activity in the process of hydrogen oxidation, to reduce the temperature of their exploitation.
