Abstract

Sodium hexa-titanate (Na₂Ti₆O₁₃) nanostructures exhibit high electrochemical surface area and unique structural properties. In this study, sodium hexa-titanate nanostructures were grown from titanium (Ti) substrate (Ti/Na₂Ti₆O₁₃) and were investigated for supercapacitance by doping oxygen vacancies and modifying with trace amounts of ruthenium (Ru) to form nanostructure composites. An electrochemical reduction method was used for inducing oxygen vacancies into the lattice structure of Ti/Na₂Ti₆O₁₃ nanocomposites to enhance electrochemical and supercapacitance properties. Several Characterization techniques like EDS, XRD and XPS were employed to identify and optimize structure property relationship to achieve supercapacitance. An enhanced specific capacitance of 3300 mF cm⁻²g⁻¹ was achieved for Ru–Ti/Na₂Ti₆O₁₃ for Ru ultra-low loading of 0.4 μg of Ru in contrast to a specific capacitance of 100 mF cm⁻²g⁻¹ observed for unmodified Ti/Na₂Ti₆O₁₃.
