The redox properties of CoPc were studied by cyclic voltammetry (CV) and square wave voltammetry (SWV) methods. The sensing performance of CoPc thin films deposited by spin coating of its solution in ethylacetate was studied against low concentrations of ammonia (0.3 to 50 ppm) by measuring changes in the films’ conductivity at different humidity. It has been shown that the CoPc-based sensor displays an improved ammonia sensing performance in terms of sensitivity, response and recovery times. Ammonia can be detected in the presence of volatile organic vapors, and its detection limit was found to be 0.3 ppm.
