Book Description
Since the discovery of carbon nanotubes by Sumio Iijima, an intensive research on carbon materials has been carried out. Carbon nanotubes and carbon nanofibers have drawn much attention due to their electronic and mechanical properties. However, because of low production capacity and high production costs at present, their applications cannot be extended until large-scale production is realized. Among the many synthetic methods, chemical vapor deposition method has advantages of high yield, high selectivity and low cost over traditional physical ones such as laser ablation and arc-discharge. High yield synthesis of one dimensional carbon nanostructures is essential for applications. In this book, an economical and environmental friendly route for the scalable production of CNTs and CNFs on easy soluble support has been discussed. The use of synthesized carbon nanotubes as catalyst support for oxidation of alcohols by Schiff base complexes and also as hydrogen storage materials is discussed in detail.

Book Description
Particular physical and chemical properties of carbon based nanomaterials (CBNs) have promised and exhibited great applications in manufacturing various nanodevices such as electron field emitters, sensors, one-dimensional conductors, supercapacitors, reinforcing fibres, hydrogen storage devices, and catalyst supports for fuel cells electrodes. Despite these amazing technical progresses, many challenges still remain in the development of synthesis methods suitable for commercial applications and fabricating novel functional nanostructures with complex architectures. In this Ph. D. thesis, one-dimensional (1D), two-dimensional (2D) carbon nanostructures, and 1D/2D hybrid of carbon nanostructures have been synthesized using various chemical vapour deposition (CVD) methods. The objective of this work is to explore the potential of various CVD methods, including specially-designed CVD techniques, such as modified spray pyrolysis, plasma enhanced CVD, and magnetron sputtering deposition. By making use of these innovative methods, high density regular and nitrogen-doped nanotubes, graphite nanosheets and assemblies have been successfully obtained on conducting and semiconducting substrates. For the modified spray pyrolysis method, systematic investigation of regular carbon nanotubes (CNTs) was conducted in terms of optimizing various experimental parameters such as hydrocarbon source, temperature, and catalyst in order to control the quality and structure of CBNs. Doping of nitrogen into carbon nanotubes was also systematically studied to enhance their electrical and mechanical properties. Interestingly, a novel structure of multi-branched nitrogen doped CNTs has been achieved by this modified spray pyrolysis method. By employing the plasma assisted CVD/sputtering hybrid system, selective growth of single and few walled CNTs have been realized. The device has also been able to produce 2D carbon nanostructures of nanosheets and a hybrid of nanosheets suspended on vertical aligned CNTs. Based on the magnetron sputtering deposition method, carbon nanowalls have been synthesized without any catalyst addition. Morphology, microstructure, and vibration properties of the CBNs were characterized by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. Carbon nanomaterials, grown in high densities on conducting and semiconducting substrates, promise great potential in building various nanodevices with different electron conducting requirements. In addition, CBNs provide a very high surface area for the support of platinum particles for use in hydrogen fuel cell electrodes.

Book Description
Fabrication and synthesis of nanostructured materials are essential aspects of nanoscience and nanotechnology. Although researchers are now able to create and tailor different nanostructured materials, the ability to precisely control the materials' sizes, shapes, and properties at the nanoscale level remains challenging. The aim of this dissertation was to develop new methods to aid researchers in overcoming these challenges. The study investigated two different methods used to create one-dimensional carbon nanostructures, i.e. carbon nanotubes and carbon nanopillars. In the first section, chemical vapor deposition method was used to grow carbon nanotubes (CNTs). Studies examining the effects of methane and hydrogen flow rates on the growth of CNTs were conducted. Results indicated that multi-walled CNTs with metallic properties could be obtained at a methane flow rates as low as 300 cc/min. At higher methane flow rates, i.e. 600-700 cc/min, semiconducting single-walled CNTs and double-walled CNTs were produced. Another phase of this section developed a new and simple CNT growth method using a solid carbon source and indicated polyacrylonitrile and nanosized SiO2 were effective in producing MWCNTs. In the second part, a new nanoimprint technique was developed to enable printing of nanostructures at sub-100nm level using various polymers. This technique inherited its high-resolution feature from traditional nanoimprint lithography, but without the use of pressure. To demonstrate, PAN nanopillar structures were printed and converted to carbon. In another phase of the part, the use of our imprint technique resulted in the creation and conversion of polysilazane nanostructures to ceramic for the first time. The final section of this dissertation is devoted to study the impact of porosity in gas diffusion layers (GDLs) on the performance of fuel cells. In one study, a new technique using SEM images to determine GDL porosity was developed. The difference between SEM calculated porosities and mercury intrusion porosimetry measurements were less than 2%. The second study characterized fuel cell performances using GDLs constructed with additional micro porous layers (MPLs) and treated with different wet proofing treatments (WPT). Results showed that when MPL is added, cell performance decreases. However, the increase in WPT in the MPL improved cell performance.
