Electrochemical characterisation - High-throughput electrocatalytic screening and single-entity nanoelectrochemistry (C01)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation ; Analytical Chemistry
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

Thin film materials libraries will be screened with respect to their catalytic HER activity with a scanning droplet cell in a defined and controlled atmosphere. This enables selection of compositions of high electrocatalytic activity and provides feedback for theoretical simulations and for the refinement of synthesis parameters. New measurement protocols will be developed to implement electrochemical surface cleaning, to collect electrolyte samples after prolonged polarization, and sequences of voltammograms or pulses to modulate the surface atom arrangements. Lift-outs by focused-ion beam will be placed on nanoelectrodes for correlative identical-location electrochemistry/transmission-electron microscopy analyses.
