摘要

摘要: 将硝酸镍溶液与氧化石墨烯溶胶混合后冷冻干燥,然后通过真空热还原得到负载过渡金属催化剂的石墨烯粉末。以天然气为碳源,在1000℃下采用化学气相沉积工艺,在石墨烯表面和边缘生长碳纳米管,碳纳米管将孤立的石墨烯片层结构有效地联接起来,组成空间互联网络结构,从而构建了电子、热能和载荷有效传输的通道。

Abstract: Graphite oxide powder impregnated with an Ni(NO₃)₂ solution was freeze-dried, thermally-reduced at 300℃ and then chemical-vapor deposition at 1000℃ was used to grow carbon nanotubes(CNTs) on graphene using methane as the carbon source.The morphology and electrical conductivities of the graphite oxide, reduced graphene and CNT-graphene hybrids were characterized.Results indicate that the density of CNTs on the graphene and the electrical conductivity of the hybrids increase with increasing Ni(NO₃)₂ concentration in the solution.Isolated graphene lamellae were connected by CNTs, giving rise to a 3D conducting network that provided conducting channels for electron transport.
