| 英文摘要 | Developing highly efficient and low-cost oxygen evolution reaction (OER) electrocatalysts is highly demanded, as OER is recognized as a key half-reaction in water splitting for producing hydrogen, however, this still remains a great challenge. Herein, we design the three-dimensional (3D) tubular hierarchical core-shell electrocatalysts for OER using a simple and highly controllable two-step method. The large-scale in-situ growth of tubular Cu(OH)2 arrays are directly grown on Cu foam (CF) at room temperature, followed by the growth of highly porous CoNi carbonate hydroxides (CH) via a low-temperature hydrothermal method on the walls of these Cu(OH)2 nanotubes (NTs). The hollow and open-structured core-shell hierarchical Cu(OH)2@CoNiCH NTs/CF electrode with large surface area, numerous mesoporous and short diffusion path can provide many active sites, fast electron transport and easy accessibility of water, leading to an excellent OER activity in an alkaline electrolyte with overpotential of 288 mV and 326 mV at a current density of 30 mA cm-2 and 100 mA cm-2, respectively, also with robust durability. This new structure would open an avenue for the advancement of highly efficient OER electrocatalysts. |
