Tailored sp2-C─F Bonding for Reversible Oxygen-Peroxide Electrocatalysis.

Rechargeable zinc-air batteries are fundamentally limited by the sluggishness of four-electron (4e-) oxygen electrocatalysis and by bifunctional catalysts that rarely combine high activity with long-term durability, resulting in substantial polarization and poor reversibility. Replacing this chemistry with O2-H2O2 inte...

DPχ: A Charge-Based Machine-Learning Potential Validated on the Pt(111)-Water Electrochemical Interface.

Electrocatalytic machine-learning potentials must simultaneously describe long-range electrostatics, nonlocal charge redistribution, and electrode-potential-dependent interfacial response, which makes their physical construction and validation particularly demanding. Here, we introduce DPχ, a charge-based machine-learn...
