Temperature-Dependent Voltammetry Reveals the Potential-Dependent Formation of Reaction Species and Their Impact on Interfacial Excess Charge during the Ammonia Oxidation Reaction on Pt
The electrocatalytic ammonia oxidation reaction (AOR) has historically garnered significant interest, since ammonia could be used as a carbon-free fuel and convenient H2 carrier. Key challenges hindering its application are the high overpotentials and rapid catalyst poisoning, which remain poorly understood. Here, we s...
