| Résumé : | Strontium doped titania (TiO2) nanoplates and titania nanoparticles were synthesized by sol−gel method. The characterization of the materials revealed the mesoporous nanoplate-like structure for Sr2+ doped TiO2. The thickness and edge length of Sr2+ doped TiO2 nanoplates were found to be 12 nm and 25−75 nm, respectively. TiO2 nanoparticles and Sr2+ doped TiO2 nanoplates showed higher surface area due to the presence of mesopores. The photocatalytic activity of TiO2 nanoparticles and Sr2+ doped TiO2 nanoplates was evaluated using 2,4-dinitrophenol (DNP) as a model pollutant. The photocatalytic activity of Sr2+ doped TiO2 nanoplates was higher than both TiO2 nanoparticles and commercial TiO2 (Degussa P-25). Sr2+ doped TiO2 nanoplates exhibited enhanced photocatalytic activity due to increases in the band gap energy and surface area. |
