一种碳纳米管及其制备方法 技术领域
本发明涉及碳材料制备及其应用领域,具体涉及一种碳纳米管的制备和应用。
背景技术
碳纳米管是由碳原子组成的一种新型的碳纳米材料,其独特的一维结构,高石墨化程度以及优异的电学和力学性能引起科研人员的广泛兴趣,尤其是在电化学能源存储和转换领域被认为具有广阔的应用前景。作为一种一维材料,直径是碳纳米管的一项重要结构参数,并有研究表明,随着改变碳纳米管的直径可以显著影响其电化学性能。
目前常用的碳纳米管制备方法主要有:电弧放电法、激光蒸发法、CVD、固相热解法等。1991年日本物理学家Iijima通过电弧放电法生首次发现了碳纳米管,这种方法技术上比较简单,但得到的碳纳米管与C 60等产物混杂,纯度不高。CVD法对设备要求简单,成本较低,是目前合成碳纳米管最可行也是最经济实用的办法。最近,直接高温碳化固相前躯体(如富勒烯碳黑、有机金属化合物、聚合物)的方法被用来制备碳纳米管,这种方法除了在操作上更为简便之外,还可以通过在前驱体中加入N、S、B化合物,使其在加热过程中原位掺杂到碳纳米管中,从而改变碳纳米管表面电子结构,能使其电化学性能得到进一步提升。然而高温热解过程中前驱体的行为难以控制,最终形成的碳纳米管通常形貌不均一,通过热解制备直径可控的碳纳米管仍存在挑战。
发明内容
本发明针对热解前躯体制备碳纳米管形貌不可控的问题,提出了一种直径可控的碳纳米管气制备方法,本发明采用以下具体方案实现:

(3)碳纳米管的制备:将步骤(2)所得前驱体在惰性气氛下进行热处理,得末端包裹金属纳米颗粒的碳纳米管。
步骤(1)中所述锌盐为硝酸锌、氯化锌、硫酸锌中的一种或两种以上,锌离子于混合溶液中的浓度为0.0125-0.1mol/L。
步骤(1)中所述机配体为2-甲基咪唑,有机配体于混合溶液中的浓度为0.1-0.8mol/L。
步骤(1)中所述混合溶液中的溶剂为甲醇、乙醇、水和DMF中的一种。
