An Electrocatalyst with Dense Single-Atom Platinum Sites for Hydrogen Evolution Reaction

Platinum (Pt) is widely used in proton exchange membrane water electrolyzers (PEMWEs) for hydrogen (H2) production due to its intrinsically high activity for the cathodic hydrogen evolution reaction (HER). However, its usage is expected to be further reduced to improve the H2 cost-competitiveness. Herein, enabled by...

Adsorbate-Directed Surface Phase Separation in Cu-Ag Catalysts.

The determination of surface configuration is essential for understanding catalytic reactivity, yet these active states cannot be reliably inferred from bulk phase diagrams. In this work, we develop a machine-learning-accelerated molecular dynamics (ML-MD) framework on the Cu-Ag system to predict and control surface st...
