| Abstract: | Developing non-noble-metal oxygen evolution reaction (OER) electrocatalysts with high performance is critical to electrocatalytic water splitting. In this work, we fabricated CoFe-layered double hydroxide (LDH) nanowire arrays on graphite felt (CoFe-LDH/GF) via a hydrothermal method. The CoFe-LDH/GF, as a robust integrated 3D OER anode, exhibits excellent catalytic activity with the need of low overpotential of 252 and 285 mV to drive current densities of 10 and 100 mA/cm2 in 1.0 mol/L KOH, respectively. In addition, it also maintains electrochemical durability for at least 24 h. This work would open up avenues for the development of GF like attractive catalyst supports for oxygen evolution applications. |
