Abstract (en)
[origin: WO2020109062A1] A method for preparing a catalytic material of an electrode for electrochemical reduction reactions, wherein said material comprises at least one active phase based on a group VIB metal and an electrically conductive support, which method comprises: a) a step of electrolysis of at least one aqueous and/or organic solution comprising at least one precursor of the active phase comprising at least one group VIB metal in order to obtain a solution comprising at least one precursor comprising at least one group VIB metal which has been partially reduced; b) a step of impregnation of said support with said solution obtained in step a) in order to obtain a catalytic material precursor; c) a step of drying said precursor obtained in step b) at a temperature below 250°C, without subsequent calcination; d) a step of sulfurization of the catalytic material precursor obtained in step c) at a temperature of between 100°C and 600°C.
