Operando Nanoscale Insights for Hydrogen Catalysts
The solution
This project addresses this measurement gap by developing two operando electrochemical scanning probe microscopy techniques: Current Imaging Tunnelling Spectroscopy in electrochemical environments (EC-CITS) and Electrochemical Kelvin Probe Force Microscopy (EC-KPFM). Both techniques are being developed as extensions of the commercially available EC-STM platform from Leiden Probe Microscopy (LPM), utilizing AMOLF's expertise in tuning fork sensor development and hydrogen catalyst science. EC-CITS provides a direct relative measure of local electrochemical reactivity. EC-KPFM provides a quantitative electronic structure proxy for relative catalytic activity.

The results
The project yields three commercial results for the Netherlands: (i) the EC-SPM platform as a globally unique research instrument with a cumulative revenue potential of >50 million euros for LPM; (ii) a scientific basis for an AMOLF spin-off that commercializes optimized HER catalysts; and (iii) an EC-SPM measuring instrument for quality control in industrial catalyst production. All three results generate intellectual property anchored in the Netherlands, strengthen Dutch market leadership in high-tech instrumentation and cleantech, and directly support the economic feasibility of Dutch offshore wind investments through improved hydrogen storage and transport.
