Abstract
Bare titanium oxides (TiO₂) and TiO₂ doped with metal (Cu, Ag) or non-metal ions (F) were synthesised by a single-step flame spray pyrolysis (FSP) method. Among these doped TiO₂ materials, the fluorine-doped TiO₂ (F-TiO₂) has high surface acidity due to the interaction of fluorine ions with the terminal titanol (TiOH) groups evidenced by the ¹H MAS NMR spectra. The F-TiO₂ reveals a higher photocatalytic activity for the oxidation of acetaldehyde even surpassing Degussa P25 (commercial TiO₂). In contrast, the flame-made Cu-doped or Ag-doped TiO₂ has a detrimental effect on the photocatalytic oxidation of acetaldehyde.
