Fast Modulation of d‐Band Holes Quantity in the Early Reaction Stages for Boosting Acidic Oxygen Evolution

Synthesis of highly active and durable oxygen evolution reaction (OER) catalysts applied in acidic water electrolysis remains a grand challenge. Here, we construct a type of high‐loading iridium single atom catalysts with tunable d‐band holes character (h‐HL−Ir SACs, ∼17.2 wt % Ir) realized in the e...
