NOVELTY - Preparing a catalytic material of an electrode, where the material comprises an active phase based on 4-70 wt.% at least one metal from group VIB and an electrically conductive support, comprises: (a) bringing water into contact with the electrically conductive support so as to obtain a wet electrically conductive support; (b) bringing the wetted electrically conductive support into contact with at least one hydrated metal acid comprising at least one metal from group VIB whose melting point of the hydrated metal acid is 20-100 degrees C, to form a solid mixture, where the mass ratio of the metallic acid and the electroconductive support is 0.1-4; (c) heating the obtained solid mixture with stirring to a temperature of the melting point of the hydrated metal acid to 100 degrees C; and (d) carrying out a sulfurization step of the material obtained at 100-600 degrees C. USE - The process is useful for preparing a catalytic material of an electrode for electrochemical reduction reactions (claimed). ADVANTAGE - The process utilizes the mixture that can be deposited on a solid or perforated collector by standard deposition techniques that are easily accessible and allowing deposition in the form of layers of varying thicknesses, ideally of the order of 10-100 mu m. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) electrode that is formulated by a preparation process comprising (1) dissolving at least one ionically conductive polymeric binder in a solvent or a mixture of solvents, (2) adding at least one catalytic material in powder form to the obtained solution in step (1), to obtain a mixture, where the steps are (1) and (2) are carried out in any order, or simultaneously, and (3) depositing the obtained mixture in the step (2) on a metallic or metallic-type conductive support or collector; and (2) electrolysis device comprising an anode, a cathode, and an electrolyte, where the device is at least one of the anode or the cathode is the electrode.
