报告摘要

Non-precious cobalt-based oxide nano-arrays with a doping of other metal ions have been reported as promising electrocatalysts for the oxygen evolution reaction (OER) of electrochemical water splitting. However, the influence of doped metal ions on their catalytic characteristic and inactivation mechanism for the OER at large current densities (>500 mA cm^-2) are rarely studied. Here, carbon fiber paper (CFP) possesses three-dimensional (3D) macroporous structure, excellent electrical performance and high stability, which is employed as the substrate material. Homogeneous CoFe, CoNi, CoMn and CoCe oxide nano-arrays grown on CFP are successfully fabricated by using the facile methods of hydrothermal synthesis and thermal decomposition. The CoFe and CoNi oxide nano-array electrodes exhibits excellent electrocatalytic activity and stability for OER at large current densities in alkaline solution. This investigation of Co-based oxide nano-arrays for clectrochemical water splitting at large current densities provides a novel viewpoint for the design and fabrication of a new nanocomposite electrode.
