Porous CoSe2@N-doped carbon nanowires: an ultra-high stable and large-current-density oxygen evolution electrocatalyst

Author affiliations

Abstract

Nitrogen doped carbon functionalized CoSe2 nanowires (CoSe2@N–C NWs), which act as potential oxygen evolution reaction (OER) catalysts with a large current density and high stability have been reported. Owing to the collaborative optimization of electrical conductivity, free adsorption energy and binding strength of OER intermediates, the prepared CoSe2@N–C NWs exhibit an enhanced 6.61-fold catalytic activity compared to the pristine CoSe2 NW electrode in 1.0 M KOH solution at the overpotential of 340 mV.
