Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.
