Fabrication of Titanium Dioxide Nanotubes with Reduced Bandgaps by Varying Electrolytic Concentrations: A Recent Study | Chapter 13 | Research Aspects in Chemical and Materials Sciences Vol. 1

 This study's main objective is to create titanium dioxide nanotubes with smaller bandgaps for hydrogen generation. Nanoscaled materials have many distinct properties than bulk materials, which has led to important scientific and technological achievements. Titanium dioxide nanotubes have a lot of promise due to their functional properties, such as a high surface-to-volume ratio. TiO2 nanotubes are produced via electrochemical anodization at a constant DC voltage of 12V for 1 hour. The sample's electrolyte is 0.25 wt% potassium fluoride dissolved in 99 percent ethylene glycol with a molarity of 0.004M. The electrolyte for samples B, C, and D was made by dissolving 0.004M of ethylene glycol in various concentrations of copper nitrate (Cu(NO3) 2 3H2O) (0.002mM, 0.003M,0.004M). Scanning of Field Emissions The creation of titanium dioxide nanotubes was studied using microscopy and photoluminescence spectroscopy, and the results were presented.
