Strong Oxide-Support Interaction over IrO₂ /V₂ O₅ for Efficient pH-Universal Water Splitting.

ABSTRACT: Constructing strong oxide-support interaction (SOSI) is compelling for modulating the atomic configurations and electronic structures of supported catalysts. Herein, ultrafine iridium oxide nanoclusters (≈1 nm) are anchored on vanadium oxide support (IrO₂ /V₂ O₅ ) via SOSI. The as made catalyst, with a unique distorted IrO₂ structure, is discovered to significantly boost the performance for pH-universal oxygen evolution reaction (OER). Based on experimental results and theoretical calculations, the distorted IrO₂ active sites with flexible redox states in IrO₂ /V₂ O₅ server as electrophilic centers balance the adsorption of oxo-intermediates and effectively facilitate the process of OO coupling, eventu
