| dc.description.abstract | Energy storage devices, such as supercapacitors, have replaced fuel cells, batteries, and traditional capacitors. Herein, a novel method is introduced to build supercapacitors from sodium hexa-titanates grown directly from a titanium dioxide (TiO2) substrate that has shown remarkable capacitance. Sodium hexa-titanates (Na2Ti6O13) nanostructures exhibit a high electrochemical surface area and unique structural properties. The research implements the use of electrochemical and characterization techniques. Furthermore, sodium hexa-titanates were investigated for supercapacitance by doping oxygen vacancies and modifying them with trace amounts of ruthenium (Ru) to form nanostructured composites. A hybrid-based nanostructure combines sodium hexa-titanate with Co3O4 nanoparticles to successfully create electrode materials. An electrochemical reduction method was used to induce oxygen vacancies into the lattice structure of Ti/Na2Ti6O13 nanocomposites and enhance electrochemical and pseudo-capacitance properties. Thus, sodium hexa-titanates have great potential to build the next generation of supercapacitors. | en_US |

| dc.description.layabstract | Supercapacitors are energy storage devices that can replace traditional batteries in a few years. Their importance is defined by faster charging, higher capacity, and energy density. Therefore, it is crucial to create new materials that can advance the applications of supercapacitors. In this thesis, a novel sodium hexa-titanate material was synthesized and studied using electrochemical techniques to evaluate the material based on its capacitance. The combined use of characterization, electrochemical techniques, and the synthesis of sodium hexa-titanates grown on the Ti substrate has been successful. | en_US |
