Abstract EN
TiO2 materials were prepared from a titanium isopropoxide precursor by sol-gel processing in water media with or without various templates (polyethylenimine or Pluronic P-123).
The photocatalytic efficiency of the samples was found to depend strongly on the use of and type of template added.
Titania/Pluronic sols resulted in homogeneous anatase TiO2—rutile with uniform particle size distribution after calcination (400°C).
Optical properties of the samples were characterized by UV-Vis spectroscopy and crystalline structures by X-ray diffraction.
A surfactant-assisted sol-gel process retarded crystallization of the anatase and rutile titania, which resulted in smaller grain sizes and presumably a larger active surface area.
The morphology of the surfaces was obtained by AFM techniques.
The highest photobleaching rate was found for samples deposited from the sol with the addition of the Pluronic P-123 surfactant, and it was almost twice as high as that for films deposited from sols with polyethylenimine.
