Spinel structured NiCo2O4 nanowire arrays supported on Ni-foam as an efficient electrocatalysts for water splitting |
| 초록 |
Developing efficient and earth abundant electrocatalyst for water splitting is of great importance with increasing clean energy demand. Herein, we report the development of an 3D hierarchical spinal structured NiCo2O4 nanowire arrays decorated on nickel foam as scaffold support, enabling superior catalytic activity towards water splitting reaction in alkaline media. This 3D hierarchical structure is binder-free which enhances the charge transfer and strong chemical coupling at the interface. Serving as an electrode catalyst, the fabricated hierarchical structure catalyzes the HER with an overpotential of 264 mV to deliver the current density of 10 mA cm-2, indicating the utilization of the material as an efficient electrocatalyst towards water splitting. |
