Electrochemically Induced Oxide‐to‐Hydroxide Transformation Enables Fast Proton Transport for Enhanced Hydrogen Evolution

Advanced Science, EarlyView.
An electrochemically induced transformation of polar MgO(111) into Mg(OH)2(001) creates a proton‐conductive hydroxide layer during hydrogen evolution. Operando synchrotron XRD and DFT reveal a low‐barrier Grotthuss proton‐hopping mechanism, establishing a feasible strategy for designing oxide‐hydroxide electrocatalysts with enhanced proton transport ...
