Titanium dioxide is a semiconductor with photo-catalytic properties and is being thoroughly investigated for its use in the degradation of harmful environmental pollutants using photo-catalytic reactions. The effects of TiO2 electrodes on degradation of methyl orange, a pollutant dye, using sunlight have been investigated. Titania nanotube, nanofiber, and nanoparticle electrodes were obtained through anodic oxidation of pure titanium sheet. Nanostructured Titania was further doped with palladium metal. Methyl orange degradation of both TiO2 and Pd-TiO2 electrodes was carried out under sunlight. The kinetic degradation was observed using UV-Vis spectroscopy. It was found that titania nanotube electrode degraded the pollutant faster than palladium doped titania nanofiber and nanoparticle electrodes. Pd-doped titania nanotube electrode was the most effective in degrading methyl orange pollutant because of the very large surface area providing higher catalytic capability.
