Oriented arrays of Co3O4 nanoneedles for highly efficient electrocatalytic water oxidation

Author affiliations

Abstract

We described an effective way to generate a Co3O4 mesocrystal array with well-developed porosity, simply by uniting a coupled interface with hydrazine treatment. Due to the fast electron transfer and sufficient active sites, the Ti mesh-supported Co3O4 nanoneedles electrode could provide a current density of 49.9 mA cm−2 at 570 mV OER overpotential and has exceptionally high stability.
