| 中文摘要:NiMoO4纳米材料在新型绿色电池、超级电容器等方面具有潜在的应用价值, 利用水热法制备 NiMoO4纳米材料, 探究不同反应温度对制备材料的表面形貌、结构和电化学性能的影响。研究结果表明, 150 ℃反应 6 h 制备的 NiMoO4 样品呈现纳米纤维形貌, 而且表现出最佳的超级电容器性能。当放电电流密度为 0.5 A/g 时, 其比电容达到 600 F/g, 即使在 10 A/g 时, NiMoO4 电极仍然能够保持 300 F/g 的比电容。此外, NiMoO4 电极表现出优异的循环寿命, 经过 6 000 次循环充放电 (放电电流密度为 5 A/g), 仍然保持其初始比电容的 97%。优异的循环稳定性使NiMoO4成为一种极具前景的高性能超级电容器材料。 |

| Abstract:NiMoO4 nanomaterials have potential applications in new green batteries, supercapacitors, and so on. The hydrothermal method was used to prepare the NiMoO4 nanomaterials. The effects of different reaction temperatures on the surface morphology, structure and electrochemical properties of the prepared materials have been investigated. The results showed that NiMoO4 samples prepared at 150 ℃for 6 h had nanofiber morphology and exhibited the best supercapacitor performance. When the discharge current density was 0.5 A/g, the specific capacitance reached 600 F/g. The NiMoO4 electrode can still maintain a specific capacitance of 300 F/g even at 10 A/g. In addition, the NiMoO4 electrode presented excellent cycle life, retaining 97% of its initial specific capacitance after 6 000 charge/discharge cycles (at a discharge current density of 5 A/g). The excellent cyclic stability of NiMoO4 makes it become a promising material for high-performance supercapacitors. |
