    • Abstract

       

      Development of hybrid electrocatalysts with high activity and good stability is crucial for oxygen evolution reaction (OER) of water electrocatalysis. In this work, cobalt oxide (Co₃O&#8324) nanowires loaded on carbon fiber paper (CFP) were synthesized via hydrothermal method and annealing. The as-synthesized Co₃O&#8324 nanowires exhibit an enhanced catalytic activity with low onset overpotential (1.52V vs. RHE) and a small overpotential of 330mV for a current density of 10mAcm⁻² with a Tafel slope of 60mV·dec⁻¹. In addition, the Co₃O&#8324 nanowires maintain its electrocatalytic activity for at least 24 h in basic media. The enhanced performance of Co₃O&#8324 nanowires/CFP can be attributed to the high conductivity of CFP, the synergistic effect of Co₃O&#8324 and carbon, and high porosity of the nanowire. This study will open new possibilities for exploring water electrocatalysis.
