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...

Guiding blind signal separation in X-ray absorption spectroscopy using supervised machine learning

Transformations under working conditions experienced by heterogeneous catalysts and other functional materials commonly result in complex, time-dependent atomistic structures, where the active species that are relevant for the functionality of the material coexist with passive spectators. Decoupling the contributions o...
