Abstract
The effect of Co3V2O8 morphology on the electrocatalytic oxygen evolution reaction (OER) activity was evaluated using one- and zero-dimensional nanostructures. The microscopic analyses reveal the existence of thin coating of nitrogen-doped amorphous carbon on the surface of Co3V2O8 nanostructures. The 1D-Co3V2O8 electrocatalyst delivers 10 mA cm-2 at overpotential of 0.350 V versus reversible hydrogen electrode for OER in 0.1 M KOH, whereas 0D-Co3V2O8 catalyst showed 0.397 V, benefited from the morphological characteristics of 1D. Moreover, the 1D-Co3V2O8 catalyst exhibits much lower OER overpotential than that of commercial noble metal oxide catalysts, RuO2 (0.41 V) and Pt/C (0.79 V). © 2015 Elsevier B.V. All rights reserved.
