Preparation and Electrocatalytic Behavior of CoTPP/RGO Nanocomposite for Dioxygen Reduction

In this paper, cobalt porphyrin combining with reduced graphene oxide (RGO) through an aromatic π-π stacking interaction made up a cobalt meso-tetraphenylprophyrin-RGO (CoTPP/RGO) nanocomposite. This composite was well characterized by scanning electron microscopy (SEM), fluorescence and UV-vis spec...

Summary:In this paper, cobalt porphyrin combining with reduced graphene oxide (RGO) through an aromatic π-π stacking interaction made up a cobalt meso-tetraphenylprophyrin-RGO (CoTPP/RGO) nanocomposite. This composite was well characterized by scanning electron microscopy (SEM), fluorescence and UV-vis spectrometry. The electrochemical behavior of CoTPP/RGO for electrocatalytic dioxygen reduction was studied on the surface of glass carbon electrode (GCE) modified with the composite by cyclic voltammetry (CVs). When the mass ratio of RGO to CoTPP is 1:1 in the composite, CoTPP/RGO film displayed superb electroreduction of oxygen.
