Atomic gold decorated polyaniline sensor for gaseous detection

Sensors for precise detection of alcohols are needed in various applications. One challenge of such sensors is to obtain high selectivity. By modifying a conducting polymer with metal catalyst, reaction kinetics can be improved. Previous research shows detection only in the liquid phase. In this paper, gas phase detection of propanol using atomic gold decorated polyaniline sensor is reported. Difference is seen from the cyclic voltammogram obtained with and without catalyst.
