3D hybrid nanostructures connecting 1D carbon nanotubes (CNTs) with 2D graphene have attracted more and more attentions due to their excellent chemical, physical and electrical properties. In this study, we firstly report a novel and facile one-step process using template-directed chemical vapor deposition (CVD) to fabricate highly nitrogen doped three-dimensional (3D) N-doped carbon nanotubes/N-doped graphene architecture (N-CNTs/N-graphene). We used nickel foam as substrate, melamine as a single source for both carbon and nitrogen, respectively. The morphology and microstructure were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, isothermal analyses, X-ray photoelectron microscopy and Raman spectra. The obtained 3D N-CNTs/N-graphene exhibits high graphitization, a regular 3D structure and excellent nitrogen doping and good mesoporosity.
将一维碳纳米管（CNT）与二维石墨烯连接起来的三维混合纳米结构，因其优异的化学、物理和电学性能而受到越来越多的关注。在本研究中，我们首次报道了一种新颖且简便的一步法，即使用模板导向化学气相沉积（CVD）来制备高度氮掺杂的三维（3D）氮掺杂碳纳米管/氮掺杂石墨烯结构（N-CNTs/N-石墨烯）。我们使用泡沫镍作为基底，三聚氰胺作为碳和氮的单一来源。通过扫描电子显微镜、透射电子显微镜、X射线衍射、等温分析、X射线光电子显微镜和拉曼光谱对其形态和微观结构进行了表征。所获得的3D N-CNTs/N-石墨烯具有高石墨化程度、规则的三维结构、优异的氮掺杂以及良好的介孔性。
