Scanning probe methods – and in particular, the combination of scanning ion conductance microscopy (SICM) and scanning electrochemical microscopy (SECM) – have emerged as unique tools for studying materials and mechanisms in complex, multistep chemical reactions such as CO2 reduction. However, they are notoriously slow in image acquisition, making them ill-suited for studying the dynamics of energy conversion processes. In this project, these two EPFL labs will develop advanced hardware and software components for a unique, fast SICM-SECM imaging method that can be easily deployed within the EPFL community, and beyond. Their method has great potential for the design of energy devices, as well as emerging cross-disciplinary applications such as the nanoelectrochemistry of single-cell signaling.
