Template Material

Polycrystalline hollow spheres and single crystalline hexagonal cylinders of MgO have been fabricated by chemical vapor deposition using ZnO and Mg as the starting materials. The Zn produced during the chemical reaction serves as template material, and vaporization of which leads to the formation of the hollow structures. The presence of trace amount of Si in the source material is identified to be critical for the existence of the stable MgO hollow structures, which otherwise would be damaged during the Zn template removal process. The same principle can be readily adopted in many other material systems and result a variety of hollow structures for catalyst, sensor and medical applications.

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.
