Structure of iridium oxide catalysts dictates performance differences for proton exchange membrane water electrolyzers

Year: 2025

Type: article

Abstract: A systematic catalyst loading study reveals the higher catalytic activity of amorphous iridium oxide arises from bulk participation via suggested electrochemical descriptors, while identifying loading-independent intrinsic electrochemical properties.
