A3: Electrochemical Writing and Correlative Characterization of Thin-Film Electrodes
Electrochemical Writing and Correlative Characterization of Thin-Film Electrodes
This doctoral project focuses on the electrochemical fabrication and multimodal characterization of functional thin-film electrodes for energy conversion applications. Using scanning electrochemical microscopy, the candidate will perform nanoscale electrochemical writing of model electrodes such as metals and metal oxides (e.g. Pt, IrOx, TiO₂@IrOx). The candidate will characterize them by microscopy and scattering techniques (e.g. SEM, 4D-STEM, EC-AFM, SECM, APT, and X-ray techniques) on identical locations to correlate their structure and reactivity. Electrochemical performance and stability will be investigated for integration into PEM electrolyzer. This project will collaborate with other projects to establish correlative workflows that will link nanoscale morphology, composition, and electrochemical activity, supported by fiducial marker systems and data fusion strategies. The project will contribute to understanding structure–property relationships and accelerate catalyst design for sustainable energy applications.
