Description
技术领域
本发明涉及一种柔性碳布负载空心球状1T-MoS2超级电容器电极材料的制备方法，具体涉及一种首先将棉布碳化制备为碳布并活化，再将球形模板嵌入碳布中，所得碳布放入钼源，硫源混合液，水热反应后去除模板以制备超级电容器用柔性碳布负载空心球状1T-MoS2超级电容器电极材料的新方法。
背景技术
可再生能源技术在解决能源危机和全球环境变化方面具有重要意义。在各种电化学能量储存和转换系统中，超级电容器近年来得到了广泛的研究，因为其具有高功率，充放电速率快，循环稳定性好等多种优势。近年来，可穿戴电子设备迅猛发展，常规形式的超级电容器已不能完全满足实际的需求，储能装置的要求扩大。各种柔性智能可穿戴电子设备朝着小巧轻便、可穿戴折叠、具有柔性的方向发展，这就要求电子设备的储能装置必须兼具柔性可弯曲、可拉伸、轻质舒适、安全稳定等特点。
碳布是双电层电容材料，它是集导电性，柔性，高稳定性，高使用寿命于一体的理想集流体和电极材料，而超级电容器中的电极是构建高效器件的关键部件，但以纯碳布作为电极的超级电容器比电容偏低，所以通过在碳布上负载其他金属，引入赝电容是来提高碳布电极比电容的有效途径。过渡金属硫化物与其相应的金属氧化物相比，电容量更高，氧化还原电位高，电导率提高，因此过渡金属硫化物受到了极大关注，在过渡金属硫化物中，二硫化钼作为热门的二维材料，具有类石墨烯的片层结构，受到了极大的关注。相对于自然界常见的半导体相的2H-MoS2，金属相的1T-MoS2具有更高的导电性，亲水性和比电容，是更为理想的超级电容器电极材料，同时，空心球的特征形状能使二硫化钼获得更大的比表面积，提高活性材料与电解液的接触面积，以提高超级电容器性能。
本专利是以棉布为碳布的原料，将其碳化为碳布，再通过氢氧化钾使碳布活化，使碳布获得更大比表面积并引入-OH基团以提升后续水热反应时的1T-MoS2负载量。本路线原料来源广泛、合成方法简便，通过调节活化试剂的量来调整碳布的导电性，比表面积和孔隙率并引入表面基团，以钼酸钠为钼源，半胱氨酸为硫源，硅球为球形模板，在200℃下水热反应合成球状1T-MoS2并负载于活化碳布上，最后去除模板获得负载于碳布上的空心球状1T-MoS2电极材料。
发明内容
本发明目的是提供一种制备柔性碳布负载空心球状1T-MoS2超级电容器电极材料的新方法。
本发明首先将棉布700～900℃碳化为碳布，将碳布与活化试剂按质量比1∶1～1∶4混合，于120℃下保温2小时活化，再将二氧化硅嵌入活化碳布，之后将所得碳布放入钼酸钠，半胱氨酸，二甲基甲酰胺和去离子水的混合液中并放置于聚四氟乙烯内衬的水热反应釜中，180～220℃下反应12～24小时，之后将产物取出，去除模板后洗涤、干燥。
本发明的特征在于：碳布同时作为集流体和电极材料，硅球作为球形模板，最终复合材料中的空心球状MoS2为金属相的1T-MoS2。
具体实施方式
实施例1：首先将棉布在管式炉中800℃，氮气保护下碳化2h，将得到的碳布与活化试剂(碳布与KOH的质量比为1∶3)混合，向其中加入适量蒸馏水混合均匀，将混合物充分浸渍后在120℃烘箱中烘干12小时，之后将产物在800℃氮气保护下的管式炉中高温活化1.5h，所得固体洗涤、干燥，得到的活化碳布进行电化学性能测试，以氢氧化钾为电解液，测得面积比容量为273F/g，循环5000次容量保持率97％。
实施例2：将已嵌入球形模板碳布，钼酸钠，半胱氨酸，二甲基甲酰胺混合液放入水热反应釜，200℃反应6小时，得到生长于碳布和球形模板上的花状微球1T-MoS2，比电容为439F/g，循环5000次容量保持率95％。
实施例3：改变水热反应时间为12小时，将已嵌入球形模板碳布，钼酸钠，半胱氨酸，二甲基甲酰胺混合液放入水热反应釜，200℃下，得到生长于碳布和球形模板上，数量减少但形状增大的纳米花状微球1T-MoS2，比电容为516F/g，循环5000次容量保持率95％。
实施例4：改变水热反应时间为24小时，将已嵌入球形模板碳布，钼酸钠，半胱氨酸，二甲基甲酰胺混合液放入水热反应釜，200℃下，得到垂直排列于实心硅球和碳布上的1T-MoS2，比电容为576F/g，循环5000次容量保持率95％。
实施例5：将实施例4所得产物去除模板后，所得的柔性碳布负载空心球状1T-MoS2电极材料测得比电容602F/g，循环5000次容量保持率91％。
