METHOD OF PRODUCING PLATINUM-BASED CATALYST AND PLATINUM-BASED CATALYST Russian patent published in 2015 - IPC B01J37/34 B01J23/42 C23C14/35 

FIELD: chemistry.

SUBSTANCE: method includes preliminary cleaning of a support by ion etching, applying an intermediate layer and subsequent magnetron sputtering from at least one platinum-based target in a vacuum in the plasma of a basic gas with addition of a reaction gas. Sputtering is carried out with power density on the sputtered magnetron target in the range of (0.004-0.17)*10⁵ W/m² with the ratio of concentration of the reaction and basic gases of 75-99%, with residual pressure of the reaction gas of 6.7-20 Pa, where the reaction gas used is oxygen. The invention also relates a catalyst obtained using said method.

EFFECT: method enables to obtain a catalytic electrode coating for electrochemical devices with high catalytic activity.
