Core-Shell Architecture Advances Oxygen Electrocatalysis

Water electrolysis is largely limited by the low activity and poor durability of the available electrocatalysts for the oxygen evolution reaction (OER) in acidic media. In this Chem issue, Qiao and co-workers rationally construct a unique core-shell Ru@IrO x nanoarchitecture to induce the desired charge redistribution and inner strain, realizing considerably acidic OER enhancement
