Electrochemistry Discovery Laboratory

Electrochemistry for interface design and engineering

We study how structure, composition and solvation at the electrode–electrolyte interface set reaction kinetics, selectivity and stability, and turn that understanding into catalysts, diagnostics and devices for hydrogen and CO₂ conversion.
