ZB 06 - Nanoelectrochemistry (W.Nogala) |
Nanoelectrochemistry group
We are focused on understanding charge transfer processes at the nanoscale level, ultimately down to individual catalytic active sides, single (bio)molecules and single charge carriers. We are also interested in electrochemical methods of nanostructured catalysts preparation and nanoscale mapping of activity.
Besides the use of traditional electroanalytical techniques, like cyclic voltammetry (CV), chronoamperometry, differential pulse voltammetry (DPV), square wave voltammetry (SWV), electrochemical impedance spectroscopy (EIS), and others, we are especially interested in the development of high spatial and temporal resolution electroanalytical methods including scanning electrochemical microscopy (SECM), scanning electrochemical cell microscopy (SECCM) and scanning ion conductance microscopy (SICM). We prepare nanoelectrodes and nanopipettes for probes and, if necessary, use them in an oxygen-free and moisture-free environment. For ultralow current measurements, we use patch-clamp amplifiers and work on converting charge transfer signal to optically readable radiation.
