Patent ID: 8092716

Claim:
A process for the preparation of a catalytic specie, said process comprising the electro-deposition of a ceramic active phase layer directly on a metallic support, the ceramic active phase layer comprising a compound of the general formula (I): [Rh x Ni y Mg l Al m (OH) 2 ] z+ (A n− z/n )kH 2 O, (I) wherein A n− is mainly a silicate or a polysilicate anion; 0≦x≦0.3; 0≦y≦0.9; 0≦l≦0.9; 0≦m≦0.5; 0≦k≦10; x+y>0; 0.5≦y+l≦0.9; x+y+l+m=1; and z is the total electrical charge of the cationic element; and the metallic support being selected from the group consisting of metallic foams which are stable at a temperature up to 1000° C.
