Description
技术领域
本发明涉及复合材料领域,具体涉及一种纳米NiCo2S4负载笼状碳球的制备方法。
背景技术
近年来,超级电容器因其具有高功率密度、充电短时间和循环寿命长等诸多优点而受到广泛关注。电极材料是影响超级电容器性能的关键因素,以RuO2等贵金属氧化物因其赝电容原理有较大的比电容值,但昂贵的价格和毒性限制了其商业化应用。一些廉价金属硫化物代替贵金属作为超级电容器电极材料成为研究热点。NiCo2S4是一种典型的尖晶石结构复合金属硫化物,存在Co3+/Co2+及Ni3+/Ni2+氧化还原电对,可以获得较高的工作电压窗口和比电容值,同时因其廉价无毒表现为极具潜力的电极材料,因此不同结构、形态、尺寸的NiCo2S4的制备受到了众多研究人员的关注(如Chen等, Nanoscale, 2013,5(19),8879;Wan等, Crystengcomm, 2013,15(38),7649; Chen等, ACS Nano, 2014,8(9),9531;Zhang等, Nanoscale, 2014,6(16),9824; Pu等, ACS Sustain. Chem. Eng. 2014,2(4),809; Zhu等, J. Power. Sources. 2015,273,584)。然而NiCo2S4作为电极材料运用于超级电容器的时候,往往存在一个问题—材料的电阻过大,导电性偏低,导致超级电容器在大电流密度下充循环冲放电不够稳定。因而,需要以一定的方式将碳材料加入到NiCo2S4电极材料中,来提高电极材料的导电性,以达到增强其电化学性能的目的。如Peng等用原位法制备NiCo2S4/石墨烯复合材料(Chemical Communications, 2013,49(86),10178); Xiao等在碳纤维上生长NiCo2S4纳米管(Nano Letter, 2014,14(2), 831); Wu等一步合成了NiCo2S4/氧化石墨复合材料(J Mater. Chem. A, 2014,2(48),20990); Ding等制备了NiCo2S4/碳布复合材料(RSC Advances, 2015,5(60),48631);中国专利公开了一种电沉积发制备NiCo2S4/碳纳米管(ZL 2015104733326)等。然而,尽管碳纳米管、石墨烯、碳纤维和碳布等结合NiCo2S4复合的电极材料具有较高的导电性和优异的超级电容性能,但这些碳纳米材料制备困难、价格昂贵,难以商业化大规模生产。

为了实现上述目的,本发明提供一种具有笼状NiCo2S4@碳球电极材料的制备方法,其特征在于,具体包括以下步骤:一、将Ni(NO3)2·6H2O和Co(NO3)2·6H2O按照 Ni2+/Co2+摩尔比为1:2溶于二甘醇和蒸馏水的混合液中搅拌均匀,再加入一定量的葡萄糖和硫代乙酰胺继续搅拌得到混合溶液;二、将所述混合溶液移入反应釜,置换N2,置换之后将N2的压强调到0.1~1MPa;将反应釜放进烘箱中,在温度为150~200℃下反应8~16h;所得产物用乙醇和蒸馏水清洗至中性,离心分离,80℃烘干得到笼状NiCo2S4@碳球电极材料。
本发明优点:具有笼状NiCo2S4@碳球电极材料结合了碳材料和笼状球形胶体的特点,具有导电性好、几何形貌规则、流动性好、孔道和尺寸可控等独特的性能;本发明方法为一步合成直接得到产物的制备方法,具有操作简单、环境友好、耗能低和成本低等优点;所获得的笼状NiCo2S4@碳球材料用于超级电容器电极时具有较高的比电容值和良好的电化学性能稳定性。
本发明采用X射线衍射技术(XRD)分析本发明制备的NiCo2S4@碳球材料的物相,采用透射电子显微镜(TEM)表征本发明制备的NiCo2S4@碳球材料的微观结构,采用电化学工作站来测试本发明制备的NiCo2S4@碳球材料的电化学性能,可知本发明成功制备出了具有较高的比电容值和良好的电化学性能稳定性的NiCo2S4@碳球电极材料。
