Titanium dioxide (TiO2) has been proven to be one of the most important and widely used photocatalyst for applications such as gas/liquid phase environmental cleaning, solar hydrogen generation, sensitized solar cell, UV filtration, etc. The biggest challenge in the applications of this semiconductor photocatalyst is its large band gap (a¼ 3.2 eV) which limits the utilizable spectrum of photons from the solar light (a¼ 4 to 5 %). To improve the optical sensitivity of TiO2 in the visible light region, the band gap of TiO2 needs to be tailored. The reduction of TiO2 band gap can be achieved by controlling of its electronic structure via two routes: changing the particle size and doping it with impurities.The real refractive index and imaginary refractive index for both the solvent and the analytes were obtained according to the usera#39;s manual for the instrument. Diffuse reflectance spectra of the powders were measured on a double beamanbsp;...
