Carbon nanotube grown on doped graphene matrix, and preparation method and application thereof

The invention discloses a carbon nanotube grown on a doped graphene matrix, and a preparation method and application thereof. In heating, stirring and high-temperature processing processes of graphene, three-dimensional graphene can be self-assembled in situ, and a specific surface area is improved; in reaction, through the generation of a nickel elementary substance catalytic carbon nanotube, thecarbon nanotube and the three-dimensional graphene are compounded. The advantages of two materials are combined to greatly improve electrochemical performance. An experiment method is safe, nontoxic,low in cost, simple in operation, and easy in implementation, and a uniform nanometer composite material can be prepared. The prepared carbon nanotube grown on the doped graphene matrix can be applied to fields including lithium ion batteries, super capacitors, electro-catalysis and the like. The method has a wide application prospect. 本发明公开一种掺杂石墨烯基体上生长的碳纳米管及其制备方法和应用，石墨烯在加热搅拌、高温处理过程中可原位自组装成三维状石墨烯，提高了比表面积；反应中生成的镍单质催化碳纳米管的生
