METHOD OF PRODUCING ANODES Russian patent published in 2014 - IPC C23F1/26 C25B11/10 C09K13/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing metal oxide anodes based on titanium with an electrocatalytic coating and can be used in different fields of applied electrochemistry in electrolysis of solutions with a wide range of mineral content. The method of making a metal oxide anode involves etching a titanium base in an acid solution with simultaneous modification of the surface thereof, forming a protective sublayer of the titanium base and depositing an electrocatalytic coating, wherein etching and modification of the titanium surface is carried out while adding hydrazine chloride to the etching solution, and the protective sublayer is formed from noble metals - iridium and platinum. Hydrazine chloride is added to the etching solution in amount of 0.1-0.3 g/l.

EFFECT: invention increases catalytic activity of anodes and corrosion resistance thereof by ensuring constant chemical and phase composition of the layer at the boundary of the titanium base and the electrocatalytic coating.
