Tunnel-structured IrOx unlocks catalytic efficiency in proton exchange membrane water electrolyzers

Abstract Proton exchange membrane water electrolyzers face challenges due to high iridium loading and sluggish oxygen evolution reaction kinetics when using conventional rutile-structured iridium oxide nanocatalysts. Here we find that iridium oxide catalysts with a specific tunnel-type crystal struc...
