Ppy (mixed spinel oxide) films Electrodeposited on Graphite for application as cathode for environment traitment by electro-Fenton.

Abstract

The composite films based on Ppy and mixed spinel oxides (Cu_1.5Mn_1.50₄ and Ni_0.3Co_2.7.0₄) have been electrodeposited on graphite substrate in aqueous solution at a current of 2 mA/cm². The composites obtained were investigated toward oxygen reduction reaction to hydroperoxyde in Na2S04 solution with different values of pH. The results showed that the graphite/Ppy(Cu1.5Mn1.504)/Ppy gives the best electrocatalytic effect at pH3 and their use as cathode for phenol treatment by Electro-Fenton had higher yield than graphite cathode without compositefilms.
