Abstract
Current sensor arrays require multiple sensing films with partial selectivities. However, preparation of multiple number of sensing films is cumbersome. Novel sensing materials such as polyaniline doped with atomic gold are favoured candidates for sensing films due to "tunable" electrocatalytic activity. This paper explores a sensor configuration of polyaniline-platinum electrodes decorated with bi-atomic gold electrocatalyst and ionic liquid as electrolyte. Electrocatalytic activity of the modified nanocomposite towards electrooxidation of alcohols is confirmed. For real-time application, suitable choice of reference electrode operational in ionic liquid electrolyte is suggested.
