This doctoral thesis presents a novel approach to methane pyrolysis using microwaves for low-GHG, energy-efficient hydrogen production and the synthesis of valuable carbon materials. The developed microwave-driven methane pyrolysis method demonstrates a hydrogen selectivity of over 90% at temperatures over 1000℃. The modular pyrolysis system facilitates hydrogen production in regions with access to natural gas and electricity. Solid carbon including bulk carbon and carbon film stands as the primary byproduct resulting from methane pyrolysis. Thus, a comprehensive analysis has been carried out to thoroughly determine the characteristics of these carbon materials. The granular bulk carbon, primarily responsible for absorbing microwave energy to drive the pyrolysis process, has been thoroughly investigated using scanning electron microscope imaging, X-ray diffraction, X-ray photoelectron spectroscopy, Raman spectroscopy, and thermogravimetric analysis. The results demonstrate high purity carbon products with a semi-graphitic structure and distinct morphological features such as a cauliflower-like texture. These characteristics have illuminated potential applications for the bulk carbon including its utilization in steelmaking, as a feedstock for graphene manufacturing, and as an anode material in sodium-ion batteries. Additionally, a carbon film synthesized through pyrolysis has been discovered, exhibiting remarkable properties akin to metallic materials such as excellent electrical conductivity. Thorough characterization of the carbon film reveals a smooth surface texture, a semi-graphitic internal structure with approximately 76 ± 24% sp2 bonding of the carbon atoms, and the presence of microcrystalline carbon fragments. The findings from the characterizations indicate the potential utilization of the carbon film in electronics, batteries, and graphene production.
