Title
(EN) DURABLE OXYGEN EVOLUTION ELECTROCATALYSTS
(FR) ÉLECTROCATALYSEURS DE DÉGAGEMENT D'OXYGÈNE DURABLES
Abstract
(EN)
Oxygen evolution electrocatalysts, electrodes using oxygen evolution electrocatalysts, and methods of making oxygen evolution electrocatalysts are provided. The oxygen evolution electrocatalyst includes an oxide electrocatalyst and a permselective amorphous layer deposited on the oxide electrocatalyst. In this regard, the permselective amorphous layer may prevent diffusion of redox ions but permit diffusion of hydroxide ions and evolved O2 through the permselective amorphous layer.
(FR)
L'invention concerne des électrocatalyseurs de dégagement d'oxygène, des électrodes utilisant des électrocatalyseurs de dégagement d'oxygène, et des procédés de fabrication d'électrocatalyseurs de dégagement d'oxygène. L'électrocatalyseur de dégagement d'oxygène comprend un électrocatalyseur d'oxyde et une couche amorphe permsélective déposée sur l'électrocatalyseur d'oxyde. À cet égard, la couche amorphe permsélective permet d'empêcher la diffusion d'ions redox mais permet la diffusion d'ions hydroxyde et d'O2 émis à travers la couche amorphe permsélective.
