| 摘 要： | 超级电容器具有比电容高、循环寿命长和绿色无污染的特点,其优异的电化学性能备受关注。本文水热合成了NiMoO4/g-C3N4复合粉体,并将粉体涂覆在泡沫镍上制备了NiMoO4/g-C3N4电极材料。结果表明,NiMoO4/g-C3N4粉体形貌主要为NiMoO4纳米棒和团状g-C3N4,且NiMoO4纳米棒生长在g-C3N4纳米片上。在NiMoO4中加入30at%的g-C3N4能降低电容体系的等效串联电阻和扩散阻抗,有利于氧化还原反应的进行。相比于其他g-C3N4含量的电极材料,g-C3N4含量为30at%的NiMoO4/g-C3N4电极材料具有更高的比电容(584.3F/g)和更好的倍率特性。

| Abstract: | Supercapacitors have the characteristics of high specific capacitance, long cycle life and green pollution-free, and their excellent electrochemical performance has attracted much attention. In this paper, NiMoO4/g-C3N4 composite powder was hydrothermally synthesized, and the composite powder was coated on foamed nickel to prepare NiMoO4/g-C3N4 electrode material. The results show that the morphology of NiMoO4/g-C3N4 powder is mainly NiMoO4 nanorods and g-C3N4 clumps, and NiMoO4 nanorods are grown on g-C3N4 nanosheets.The electrochemical performance test results show that adding 30at% g-C3N4 to NiMoO4 can reduce the equivalent series resistance and diffusion impedance of the capacitor system, which is beneficial to the oxidation-reduction reaction. Compared with other electrode materials with g-C3N4 content, NiMoO4/g-C3N4 electrode materials with a g-C3N4 content of 30at% have higher specific capacitance (584.3F/g) and better rate characteristics. |
