FIELD: chemistry.
SUBSTANCE: invention relates to an electrode having a) an electrode substrate containing M(n+1)AXn, where M is a group IIIB-VIB or VIII metal or a combination thereof, A is a group III-VIA element or a combination thereof, X is carbon, nitrogen or a combination thereof, where n equals 1, 2 or 3; and b) an electrocatalytic coating deposited on said electrode substrate, which is selected from b.1) a metal oxide and/or a metal sulphide which contains ByC(1-y)Oz1Sz2, where B is at least one of ruthenium, platinum, rhodium, palladium, iridium and cobalt, C is at least one valve metal, y equals 0.4-0.9; 0<=z1, z2<=2 and z1+z2=2; b.2) a metal oxide which contains BaCgDhEi, where B is at least one of ruthenium, platinum, rhodium, palladium and cobalt, C is at least one valve metal, D is iridium, E is Mo and/or W. Wherein f equals 0-0.25 or 0.35-1, g equals 0-1, h equals 0-1, i equals 0-1, wherein f+g+h+i=1; b.3) at least one noble metal; b.4) any alloy or mixture containing iron-molybdenum, iron-tungsten, iron-nickel, ruthenium-molybdenum, ruthenium-tungsten or mixtures thereof; b.5) at least one nanocrystalline material. The invention also relates to a method of making an electrode, use thereof and a method of producing an alkali metal chlorate and an electrolysis cell for production thereof.
EFFECT: improved operational characteristics of the electrode.
