Title: A comparative study on mesoporous TiO2 film deposited onto diverse glass substrates for photooxidation of acetaldehyde in gas phase
Biography: Adel A Ismail
Mesoporous TiO2 films were dip-coated diverse conductive glass substrates such as Indium Tin Oxide (ITO) and F-doped Tin Oxide (FTO) as well soda-lime glass (SL). The mesoporous TiO2 films were assessed for their photodegradation for CH3CHO oxidation in gas phase as a probe molecule and compared with both nonporous TiO2 film deposited on FTO and commercial Pilkington Glass. The thickness and surface areas of the mesoporous TiO2 films was determined to be around 228±10, 184 ±15 and 205 ±15 nm and 215, 352 and 295 m2/cm3 deposition on SL, FTO and ITO, respectively. The prepared mesoporous TiO2 film deposited on SL, FTO and ITO are more photonic efficiency than nonporous TiO2 film and Pilkington Glass. The photonic efficiency of mesoporous TiO2 film is the following order FTO> ITO > SL. The photonic efficiency of TiO2/FTO is greater 21 and 3 times than that commercial Pilkington Glass ActivTM and nonporous TiO2/FTO, respectively. In addition, the outstanding photocatalytic activity of mesoporous TiO2/FTO substrate is shown in recycling tests in which no significant reduce in the photonic efficiency was recognized after five repetitive times for 10 hours continuously, indicating a promising materials for potential applications.
