Electrocatalytic Reduction of Cobalt Oxide Spinel for Oxygen Reduction Reaction in Alkaline Media
Harsha P. Uskaikar -
Abstract:The cathode material were prepared by dispersing Co3O4 on vulcan carbon in situ and manually grinding in pestle and mortar. Co3O4 prepared by hydrazine based combustion method showed nanocrystalline nature. Surface area was found to increase on dispersing Co3O4 on vulcan carbon by manually grinding it in pestle and mortar. The kinetics of the oxygen reduction reaction (ORR) was studied on Co3O4/C electrodes in KOH electrolyte by using cyclic voltammetry and steady state polarization measurements using Hg/HgO… Show more
