Gold Nanodots-Decorated Nickel Hydroxide Nanoflowers for Enhanced Electrochemical Oxygen Evolution Activity |
| 초록 |
Nanohybrids composed of noble metal nanoparticles and transition metal hydroxides often possess catalytically active sites that are beneficial for OER performance. In this study, we report a successful synthesis of Ni(OH)2 nanoflowers with a high degree of crystallinity and uniformity. The as-prepared Ni(OH)2 nanoflowers are employed as templates for effective and controllable loading of Au nanodots to obtain Ni(OH)2@Au nanohybrids. An examination of the OER activity reveals that Ni(OH)2@Au exhibits a considerably lower overpotential value (390 mV) at a current density of 5 mA cm2 and a smaller Tafel slope (120 mV dec–1) than those of Ni(OH)2 (540 mV and 324 mV dec–1, respectively). |
