The emerging carbon-based materials possess properties that depend on the way how carbon is structured at the nanoscale. Synthesis of novel three dimensional (3D) nanostructures of carbon compound would be an important advance for fundamental research and various applications. In this work, we discuss the possibility of fabricating complex 3D nanostructures by growing carbon-compounds on pre-synthesized nanostructured zeolites templates by chemical vapor deposition (CVD) and then etching away the zeolites. We study two types of zeolites structures, NaX and NaY. We systematically study the roles of different parameters, such as the composition, morphology and crystallinity of the material on zeolites-template, as well as the CVD growth temperature and different carbon sources to synthesize the carbon-compound on zeolites. The same time we will shows that polycrystalline nanostructures start to growth at low temperature of 500 oC. However we observed that the crystallinity of the nanostructures was affected by the selection of reactive carbon source that is deposited on the zeolite from lower temperatures. Furthermore, the selection of a zeolite is also important, as type X are shown to be more resistant to thermal damage than their type Y. We could successfully remove the zeolite templates to form free-standing carbon-based hollow nanostructures. This 3D structure could be used in water or air filters in a potential biological application for removal of bacteria in conditioner airs or and plants of water treatments. The results presented in this analysis could to help the synthesis of other 3D-carbon nanostructures
