Insights Into the Oxygen Evolution Reaction on an Mn‐Bearing Hematite Electrocatalyst in an Acidic Electrolyte
Platinum group metal‐free catalysts have attracted significant attention due to the high cost and scarcity of iridium for the oxygen evolution reaction (OER) in acidic media. However, the fundamental understanding of catalyst formation and active species under acidic conditions remains limited. In this work, iron–manga...
