摘要
通过用改进的Hummers法、化学氧化聚合法和凝胶法制备合成聚吡咯氧化石墨烯钌-二氧化钌[Ru-RuO_(2)/PPy/GO(RPG-15)]纳米材料,通过X射线衍射仪、扫描电镜等仪器对RPG-15纳米材料进行表征。结果表明:金属元素以颗粒态形式均匀锚定在PPy/GO纳米片表面以及夹层之中,形成一种多层次复合的纳米结构,RPG-15纳米材料展现出的优秀的储能能力。RPG-15纳米材料制备的工作电极在1A/g的电流密度下,比电容值可达到319.2F/g,说明其具备一定的倍率性能,但尚有改善空间,在3000次(10A/g)的长循环充放电测试后,最终的容量保有率达到84.8%,展现了其在储能场景中的显著潜力。
The Ru-RuO_(2)/PPy/GO(RPG-15)nanomaterial was synthesized using the modified Hummers method,chemical oxidative polymerization,and the gel method.Characterization of RPG-15 was conducted using X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results revealed that metal elements were uniformly anchored as particles on the surface and within the interlayers of PPy/GO nanosheets,forming a multi-level composite nanostructure.The RPG-15 nanomaterial exhibited excellent energy storage capability.The working electrode fabricated from the RPG-15 nanomaterial achieved a specific capacitance of 319.2F/g at a current density of 1A/g.This indicated that the material possessed a certain rate performance,though there was still room for improvement.After 3000 cycles of long-term charge-discharge tests at a current density of 10A/g,the final capacity retention rate reached 84.8%,demonstrating its significant potential in energy storage scenarios.
