Abstract


The composite films based on Ppy and mixed spinel oxides (Cu1.5Mn1.5O4 and Ni0.3Co2.7O4) 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 Na2SO4 solution with different values of pH. The results showed that the graphite/Ppy(Cu1.5Mn1.5O4)/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 composite films.
