- Description
- Co-deposition of palladium and platinum (PdPt) nanoparticles on the conducting polymeric ?lm of Polyaniline (PAn) modified carbon fiber paper (CFP) electrode was carried out by using eletrochemical method. The modified electrode has been used for the oxidation of 4-pyridinemethanol. The electrochemical properties of fabricated multi-layered ?lms on carbon fiber paper (Pd-Pt/PAn/CFP) were studied by electrochemical AC impedance spectroscopy and cyclic voltammetry (CV). Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) characterization technics were environmentally benign and sustainable are used to analyze the structural properties of modified multi-layered electrode. The relative sizes and distribution of the nanoparticles on the electrode surface were analyzed using Scanning electron microscopy (SEM) and optical profilometry characterization techniques. Electrochemical studies by CV showed that the PdPt/PAn/CFP electrode had better electrochemical activity similar to PAn/CFP and Bare CFP electrode towards extensive electrochemical oxidation of 4-pyridinemethanol in presence of TEMPO (2,2,6,6-Tetramethylpiperidinyl-1-oxyl) in aqueous acidic medium. 2021
