Synthesis of P Doped EDTA-Co Structure and Synergistic Effect of ORR as Electrochemical Catalyst

Abstract

In this study, we successfully developed an electrochemical cathodic catalyst with a previously unreported structure. In essence, a new material was fabricated by doping EDTA-Co with P. EDTA has six ligand sites and forms an octahedral structure through six coordination bonds with transition metals. In addition, by doping hetero atoms, the atomic and spin charge density of the catalyst surface are changed to lower the adsorption energy of oxygen, which leads to more favorable reactions and enhances the catalytic properties. Co and P were added to EDTA to synthesize a successful catalyst, and testing confirmed an increase in electrochemical performance due to the addition of Co and P. Moreover, this work demonstrates that the synergy effect exceeds that of simply adding Co and P.
