WebPlatinum group metal (PGM)-free oxygen reduction reaction (ORR) catalysts are of utmost importance for the rapid development of anion-exchange membrane fuel cell (AEMFC) technology. In this work, we demonstrate the improved ORR performance and stability of Co and Fe oxide-decorated/N-doped reduced graphene oxide (CoOx-Fe3O4/N-rGO) prepared … WebO X 2 has a double bond in its normal form. That is O = O. There are no unpaired electrons in this case are there since there are 2 lone pairs on each oxygen. However 1 resonance structure would be O − O (result of homolytic cleavage of double bond) where each O is a free radical (a negatively charged one at that).
