The invention relates to an electrode comprising a) an electrode substrate comprising M(n+1) AX n, where M is a metal of group IIIB, IVB, VB, VIB or VIII of the periodic table of elements or a combination thereof, A is an element of group IIIA, IVA, VA or VIA of the periodic table of elements or a combination thereof, X is carbon, nitrogen or a combination thereof, where n is 1, 2, or 3; and b) an electrocatalytic coating deposited on said electrode substrate, said coating being selected from at least one of b.1) a metal oxide and/or metal sulfide comprising B y C(1-y)O z1S z2, wherein B is at least one of ruthenium, platinum, rhodium, palladium, iridium, and cobalt, C is at least one valve metal, y is 0.4-0.9, 0 <= z1, z2 <= 2 and z1+z2=2; b.2) a metal oxide comprising B f C g D h E i, wherein 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 is 0-0.25 or 0.35-1, g is 0-1, h is 0-1, i is 0-1, wherein f+g+h+i=1; b.3) at least one noble metal; b.4) any alloy or mixture comprising 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 process of producing the electrode, and the use thereof. The invention also relates to a process of producing alkali metal chlorate and an electrolytic cell for production thereof. |
