Energy issues have been of primary global concerns due to the depletion of fossil fuels and the increase in demand for energy storage in our daily lives. Among alternative energy sources, supercapacitors have been of great interest in electrochemical energy storage devices due to their fast charge-discharge capability, high specific capacitance, long life, and safety. The developments in novel nanostructured electrode materials with high power and energy densities as well as their simple fabrication process for electrochemical energy storage applications are undeniably essential. Therefore, this present work has been focused on developing a novel multifunctional titanium oxynitride (TiNO) material in the form of one-dimensional nanowires as a potential electrode material for supercapacitors. The dissertation also demonstrates the fundamental understanding of the growth mechanism of TiNO nanowires by systematically investigating the influences of the crucial growth parameters (e.g., gold catalyst size, nitrogen gas, and the number of laser pulses) on the nanowire structures. Our multifunctional titanium nitride nanowires were successfully prepared and optimized by a pulsed laser deposition method. The present electrochemical studies have shown that the TiNO nanowires possess a pseudocapacitive-type behavior for their charge storage mechanism. Importantly, the TiNO nanowires can achieve an outstanding specific capacitance up-to 3,355 mF/cm2 at 2 mV/s, which is among the highest values reported in thin film-based electrode materials. Our findings also show that the electrochemical performance of TiNO nanowires is significantly superior to the TiNO film due to the enhancement of high effective surface areas for ion diffusion at an electrode-electrolyte interface. Plus, it shows a good electrochemical cyclic stability and has the characteristics of fast charge and discharge capability. These findings can promisingly pave the way to employ TiNO-based nanowires as a potential electrode for future uses in high-performance supercapacitors.
