Abstract
Herein, we have report electrochemical synthesis of polyanilne (PANI) films on indium doped tin oxide (ITO) glass substrate using cyclic voltammetry. The formation of PANI was determined by powder x-ray diffraction = PXRD and Fourier-Transform Infrared Spectroscopy = FTIR measurements. The surface morphology of the electrochemically grown PANI on ITO glass (ITO/PANI) was found to be rod like as confirmed by Field Emission Scanning Electron Microscopy = FE-SEM analysis. Further, this prepared film was used as working electrode for the electrochemical sensing of p-nitrophenol (p-NP). The ITO/PANI based p-NP sensor exhibited interesting detection limit of 2 ± 0.5 μM. The performance of ITO/PANI electrode was also found selective and reproducible using cyclic voltammetry.
