Title
(EN) METHOD FOR PREPARING A CATALYTIC MATERIAL FOR ELECTROCHEMICAL REDUCTION REACTIONS, CONTAINING A GROUP VI METAL AND A GROUP VIII METAL, OBTAINED BY CHEMICAL REDUCTION
(FR) PROCEDE DE PREPARATION D'UN MATERIAU CATALYTIQUE POUR DES REACTIONS DE REDUCTION ELECTROCHIMIQUE COMPORTANT UN METAL DU GROUPE VI ET DU GROUPE VIII OBTENU PAR REDUCTION CHIMIQUE
Abstract
(EN)
The invention relates to a method for preparing a catalytic material of an electrode for electrochemical reduction reactions, said material comprising an active phase based on a group VIB metal and a group VIII metal, and an electrically conductive substrate, said method comprising: a) a step of forming particles of a catalytic precursor containing a group VIII metal, at least partially in metallic form, on the substrate; b) a step of bringing the catalytic precursor obtained in step a) into contact with an aqueous and/or organic solution containing a catalytic precursor comprising a group VIB metal; c) a step of drying the catalytic precursor obtained in step b) at a temperature of less than 250°C, without subsequent calcination; and d) a step of sulfiding the catalytic precursor obtained in step c) at a temperature of between 100°C and 500°C.
