| Abstract Scope |
The present research is aimed at the development of low-dimensional titanium oxynitrides, TiNxOy (TiNO), thin films and nanowires for electrochemical supercapacitor and solar water-splitting applications. The advantages of TiNO over other transition metal oxides are associated with the less electronegative and more polarizable characteristics of nitrogen relative to that of oxygen. The synthesis of high-quality multifunctional 2-dimensional (2D) TiNO thin films and 1-dimensional (1D) TiNO nanowires has been accomplished using a binder-free non-clean room-specific pulsed laser deposition method. The electrochemical supercapacitor measurements on the TiNO system using cyclic voltammetry have shown that the specific capacitance values for the TiNO nanowire samples (2,725 mF.cm-2) are nearly six times more than that of the TiNO thin film samples (400 mF.cm-2). The supercapacitor values amongst the highest values reported for the recently top-tier nanoscale electrode materials. |
