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

Advanced Functional Materials, EarlyView.The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...
