Nanostructured photoanodes were made from titanium dioxide (TiO2)
nanoparticles doped with Nitrogen and iron, the effect of this modifcation on
optical properties of TiO2 nanoparticles to shift its absorption edge toward
visible light region was studied. TiO2 nanoparticles were obtained by a green
biological route, using an extract derived from leaves of lemon grass as reducing
agent; by using a wet impregnation mechanism these nanoparticles were doped
and supported as thin films by dr Blade technique. The synthesized material was
characterized by Fourier transform infrared spectroscopy (FT-IR), Scanning
electron microscopy (SEM), UV-VIS diffuse reflectance spectroscopy (UV-
VIS/DRS). FTIR characterization have been made to confirm the formation of
TiO2. Morphological properties and particle size were identified by SEM
micrographs. A decrease in the band gap energy it was observed with doped by
UV-VIS/DRS.
