Abstract
The use of fast scan cyclic voltammetry (FSCV) to generate images in scanning electrochemical microscopy is demonstrated. In the FSCV-SECM method a cyclic voltammogram is acquired at each grid point of the scanned area. Thus, each point in the SECM image is a data array rather than a single value. This provides a significant increase in the amount of data collected per scan and provides the ability to make images of multiple analytes per scan. In addition, the use of cyclic voltammetry allows images based on adsorptive as well as diffusional processes. In this paper, we describe the FSCV-SECM experiment and equipment, we show that FSCV-SECM can resolve multiple chemical species in a single scan, and we demonstrate that cathodic-stripping voltammetry can be used to image the concentration profiles of halide ions.
