Carbon nanomaterials exhibit many remarkable electrical and physical properties. An ongoing challenge associated with specific novel carbon nanomaterials, such as graphene, is the development of large-scale production methods at low cost. The broad objective of this work is to investigate flame synthesis of carbon nanomaterials, specifically graphene and carbon nanotubes (CNTs), using open-atmosphere processing, with an eye towards scalability. An experimental study using a novel setup, based on multiple inverse-diffusion flames is undertaken to investigate the direct flame-synthesis of CNTs and graphene on metal substrates. Few-layer graphene (FLG) is grown on copper and nickel substrates at high rates using the novel flame-synthesis burner. Substrate material (i.e. copper, nickel, cobalt, iron, and copper-nickel alloy), along with its temperature and hydrogen pretreatment, strongly impacts the quality and uniformity of the graphene films. The growth of FLG occurs in the temperature range 750-950°C for copper and 600-850°C for nickel and cobalt. For iron, the growth of graphene is not exclusively observed. CNT growth is observed on a number of substrates. Transitional growth between CNTs and graphene films occurs on nickel and nickel alloys, depending on composition and temperature. For nickel, copper-nickel, nitinol, and Inconel substrates, CNTs grow at 500°C. The transitional growth to few-layer graphene is observed on nickel, copper-nickel and Inconel by changing the substrate temperature to 850°C. The growth of graphene is not observed on nitinol for the examined experimental conditions. The growth of few-layer graphene films and CNTs are also investigated using various metal-oxide spinels as catalysts. The growth of CNTs is examined on NiAl2O4, CoAl2O4 and ZnFe2O4 using counterflow diffusion flame and multiple inverse-diffusion flames, while the growth of graphene is examined on CuFe2O4 using multiple inverse-diffusion flames. Finally, the growth of CNTs and iron oxide is studied on stainless steel. At low temperatures (500oC) the growth of [alpha]-Fe2O3 is observed, while at higher temperatures (850oC) the growth of CNTs is observed. Additionally, by following a two-step growth process, where the temperature is changed from 500oC to 850oC, the growth of CNTs and [gamma]-Fe2O3 occurs.

Carbon nanotubes belong to new nanomaterials and have been known for almost 20 years, but their history is somewhat lengthier. They have been identified as promising candidates for various applications.High-temperature preparation techniques are conventional techniques for the synthesis of carbon nanotubes using arc discharge or laser ablation, but today these methods are being replaced by low-temperature vapor deposition techniques, since orientation, alignment, nanotube length, diameter, purity, and density of carbon nanotubes can be precisely controlled. The synthesis of carbon nanotubes by chemical vapor deposition on catalyst arrays leads to nanotube models grown from specific sites on surfaces. The controlled synthesis of nanotubes opens up interesting possibilities in nanoscience and nanotechnologies, including electrical, mechanical and electromechanical properties and devices, chemical functionalization, surface chemistry and photochemistry, molecular sensors, and interfacing with moderate biological systems.Carbon nanotubes are used in many applications due to their unique electrical, mechanical, optical, thermal, and other properties. Conductive and high-strength composite materials, energy saving and energy conversion devices, sensors, visualization of field emissions and sources of radiation, means for storing hydrogen, and nanoscale semiconductor devices, probes, and interconnections are some of the many applications of carbon nanotubes.

The study of nanostructures has become, in recent years, a theme common to many disciplines, in which scientists and engineers manipulate matter at the atomic and molecular level in order to obtain materials and systems with significantly improved properties. Carbon nanomaterials have a unique place in nanoscience owing to their exceptional thermal, electrical, chemical, and mechanical properties, finding application in areas as diverse as super strong composite materials, energy storage and conversion, supercapacitors, smart sensors, targeted drug delivery, paints, and nanoelectronics. This book is the first to cover a broad spectrum of carbon nanomaterials, namely carbon nanofibers, vapor-grown carbon fibers, different forms of amorphous nanocarbons besides carbon nanotubes, fullerenes, graphene, graphene nanoribbons, graphene quantum dots, etc. in a single volume.

The synthesis of carbon nanotubes (CNTs) and metal-oxide nanowires (e.g. ZnO, WO2.9) are examined experimentally by inserting probes into various flame geometries at atmospheric pressure. The main probed-flame configurations are the inverse co-flow diffusion flame (IDF) and the counter-flow diffusion flame (CDF), which are compared with each other to assess the translatability of local synthesis conditions in producing the same growth attributes and morphologies. The CDF is characterized using laser-based spontaneous Raman spectroscopy (SRS), and validated with simulations using detailed chemical kinetics and transport. SRS is used to measure local conditions in the 2-D axi-symmetric IDF. Properties of the as-synthesized nanostructures are determined by field-emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDXS), and resonance Raman spectroscopy (RRS). Various morphologies of CNTs are grown catalytically on metal-alloy substrates of different compositions (i.e., Fe, Fe/Cr, Ni/Cu, Ni/Ti, Ni/Cr, Ni/Cr/Fe), as well as on metal-oxide solid solutions (i.e. NiAl2O4, CoAl2O4 and ZnFe2O4). Vertically well-aligned multi-walled CNTs (MWNTs) with uniform diameters are obtained from Ni/Cr/Fe and Ni/Ti alloys. CNTs produced from ZnFe2O4 substrates are found to be a mixture of MWNTs and single-walled carbon nanotubes (SWNTs) with at least 30% SWNTs by number. Effects of local gas-phase temperature, substrate temperature, carbon-based precursor species concentrations, and substrate voltage bias on CNT formation, diameter, growth rate, yield, density, and morphology are investigated. Aligned single-crystal tungsten oxide nanowires with diameters of 20-50nm are grown directly from tungsten substrates at high rates, with local gas-phase temperature and chemical species specified at the substrate for self-synthesis. Voltage bias is shown to dramatically alter the morphologies of the as-synthesized WOx nanomaterial. Single-crystalline ZnO nanowires are grown directly on zinc-plated steel substrates at high rates with no catalysts. Larger-diameter (>100nm) nanowires are produced at higher temperatures; while smaller-diameter (25-40nm) nanowires are produced at lower temperatures, and only on the fuel side of the reaction zone. Reactions with H2O appear to be the dominant route for nanowire synthesis. Nanoribbons and other nanowire-based morphologies are also found and discussed.
