Nanometerials Synthesis
One dimensional (1D) nanostructures of various metal oxides are of particular interest in various applications such as gas sensors, capacitors, photo-catalysts, solar cells, anti-reflection coatings, optical coatings and lithium ion batteries. Wide variety of fabrication routes such as hydrothermal, electrospinning, anodization, UV lithography and thermal oxidization have been developed for synthesizing 1D metal oxide nanostructures. Among all these routes, thermal oxidation and carbon assisted thermal evaporation routes are attractive for mass production due to its simplicity, scalability and low production cost.

In this research, nanowires of copper oxide (CuO), titanium dioxide (TiO2), core-shell TiO2-Al2O3, zinc oxide (ZnO) were synthesized on Cu, Ti, Ti-6Al-4V (Ti64) and brass (Cu - 37.2 wt% Zn) substrates, respectively by thermal oxidation. The oxidation parameters were optimized by investigating the effects of alloy microstructure, temperature, oxidation atmosphere, gas flow rate, residual stress and oxidation time.
Beside this, core-shell SnO2-ZnO, zinc stannate / zinc oxide (Zn2SnO4/ZnO) nanowires synthesized on quartz and alumina substrates, respectively by carbon assisted thermal evaporation process. Functional nanoparticles were loaded on the nanowires by wet reduction process.
The resultant nanostructures were investigated using X-ray diffractometer, X-ray photoelectron spectroscope, Raman spectroscope, transmission electron microscope, scanning electron microscope etc.
