Process for the preparation of a catalytic specie consisting essentially of a metallic support, which is coated with a ceramic active phase layer, mainly compound of the general formula (I):[RhNiMgAl(OH)](A)kHO,&#x2003;&#x2003;(I)wherein Ais mainly a silicate or a polysilicate anion; 0&#x2266;x&#x2266;0.3; 0&#x2266;y&#x2266;0.9; 0&#x2266;l&#x2266;0.9; 0&#x2266;m&#x2266;0.5; 0&#x2266;k&#x2266;10; x+y&#x3e;0; 0.5&#x2266;y+l&#x2266;0.9; x+y+l+m=1; and z is the total electrical charge of the cationic element or a compound of the general formula (II):[AA'][BNiRh]O&#x2003;&#x2003;(II)wherein A and A&#x2032; are different and are selected from the Lanthanide or the Actinide families or from the group IIof the Mendeleev's periodical table of elements; B is selected from the transition metal groups of columns IIIb, IVb, Vb, VIb, VIIb, Ib and IIb and group VIIIb of the Mendeleev's periodical table of elements; 0&#x2266;x&#x2266;0.7, 0&#x2266;y&#x2266;0.5, 0&#x2266;x+y&#x2266;0.8, 0&#x2266;z&#x2266;1 andis the sub stoechiometric value of oxygen to obtain the electric neutrality of the Perovskite compound; said process essentially consisting in a step (a) of electro-deposition of said ceramic active phase on said metallic support. Use of said catalytic specie as a catalyst oxidation of gaseous hydrocarbons, to produce synthesis gas.
