Facilities - Scanning Electrochemical Microscope - CHI
Capabilities:
- High resolution electrochemical mapping of electrode surfaces
By detecting reactions that occur at a ultramicroelectrode tip, as it is scanned near a surface, the SECM is used to obtain 2D and 3D electrochemical activity images of the electrode surfaces. The tip is Pt, Au or C based with a diameter ranging from 25 µm to 10 µm. The SECM can operate in various operational modes such as feedback, generation/collection, competitive etc.
- Measurements of the reaction rates
The SECM is used for studying the electrode kinetics based on the regeneration of the electroactive species on the tip while it slowly approaches the electrode surface.
