Constructing Built-in Hydroxyl Relay Through Ru/RuO2 Interfaces for Efficient PEM Water Electrolysis.
As promising non-iridium alternatives, RuO2-based catalysts demonstrate superior acidic oxygen evolution reaction (OER) activity, however, their poor stability in acidic electrolyte remains a critical bottleneck hindering their application in proton exchange membrane water electrolysis (PEMWE). Herein, we construct a R...
