Macroporous electrospun indium tin oxide electrodes for spectroelectrochemical analysis

Abstract : There is a growing interest in finding new and commercially viable methods of performing a spectroelectrochemical analysis which combines electrochemical and spectral techniques. For this purpose, an electrode material that is transparent and conductive needs to be prepared. In this work, such electrode was prepared by electrospinning which is a technique capable of forming very thin fibers with high surface area. Those electrodes were also covered with additional layer of porous and functionalized silica to maximize the surface area and introduced additional sensing properties. This material was used in the detection of methylene blue which is an industrial dye and an environmental pollutant. It was found that using such electrode it was possible to detect concentrations that are smaller than the harmful environmental levels. Finally, the layers were also used with success to generate luminescence which is opening new prospects for the design of spectroelectrochemical sensors
