Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

Advanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...
