Abstract[English]
The present invention provides a process for preparing a catalyst, as well as a catalyst, the catalyst comprising an oxygen evolution reaction electrocatalyst, a hydrogen oxidation reaction electrocatalyst, and a particulate solid support, wherein the oxygen evolution reaction electrocatalyst and the hydrogen oxidation reaction catalyst are both supported on the particulate solid support. In the process, the oxygen evolution reaction electrocatalyst is deposited before the hydrogen oxidation reaction electrocatalyst by using a halide-free metallate as precursor.[French]
La présente invention concerne un procédé de préparation d'un catalyseur, ainsi qu'un catalyseur, le catalyseur comprenant un électrocatalyseur de réaction de dégagement d'oxygène, un électrocatalyseur de réaction d'oxydation d'hydrogène, et un support solide particulaire, l'électrocatalyseur de réaction de dégagement d'oxygène et le catalyseur de réaction d'oxydation d'hydrogène étant tous deux supportés sur le support solide particulaire. Dans le procédé, l'électrocatalyseur de réaction de dégagement d'oxygène est déposé avant l'électrocatalyseur de réaction d'oxydation de l'hydrogène à l'aide d'un métallate exempt d'halogénure en tant que précurseur.
