A facile electrochemical oxidation of pyridyl carbinol based on Manganese dioxide-Phosphate (MnO 2 -Pi) was fabricated by electro-deposition of MnO 2 -Pi on Porous carbon nanospheres (PCN) modified carbon fiber paper (CFP) electrode. A simple working electrode was developed initially by coating Monkey Pod (MP) derived PCN on carbon fiber paper (CFP) electrode. Voltammetric deposition of MnO 2 -Pi on PCN/CFP electrode was carried out in an electrolyte containing phosphate buffer and KMnO 4 . The modified electrodes (PCN/CFP and MnO 2 -Pi-PCN/CFP) were characterized by different physicochemical methods and electroanalytical techniques like cyclic voltammetry and AC impedance spectroscopy. Inorganic phosphate (Pi) and MnO 2 centers present on PCN/CFP electrode plays a major role towards oxidation of pyridyl carbinol electrochemically. The proposed MnO 2 -Pi-PCN/CFP electrode was effectively applied for the electrochemical oxidation of pyridyl carbinol in TEMPO medium.
