INDIRECT OXIDATION OF PHENOL ON GRAPHITE ON NI0.3 Co2.7O4 SPINEL ELECTRODES IN ALKALINE MEDIUM

We studied the oxidation of phenol by HO2- ions obtained from the oxygen reduction reaction (ORR) on pyrolytic graphite and on Ni0.3Co2.7 O4 spinel oxide in 1M KOH at 25C. Phenol degradation was achieved by using the controlled potential electrolysis of saturated O2 solutions under batch and laminar...
