Au-Doped CuOx Nanoparticles as Electrocatalysts for Oxygen Evolution Reaction
Source abstract
Abstract
Here, we report an efficient Au-doped CuOx nanoparticle electrocatalyst (Au-CuOx-80) for oxygen evolution reaction (OER). The Au-CuOx-80 catalyst is prepared using a galvanic replacement reaction and exhibited excellent catalytic activity for OER in 1 M Na2CO3 solution (pH = 11.4) with an overpotential of 380 mV and a Tafel slope of 74 mV dec–1 at a current density of 10 mA·cm–2 and long-term stability up to 24 h. We attribute the superior electrocatalytic performance to the high electronegativity of Au doped inside the Cu2O cubes.
