Silver-doped TiO2 prepared by microemulsion method: surface properties, bio- and photoactivity
Otrzymane fotokatalizatory typu Ag-TiO2 wykazywały wyższą aktywność w reakcjach fotodegradacji fenolu w obecności promieniowania z zakresu UV oraz światła widzialnego w porównaniu z komercyjnym katalizatorem Degussa P25 oraz czystym niedomieszkowanym TiO2, otrzymanym w mikroemulsji woda-AOT-cykloheksan. Powierzchnia właściwa (BET) otrzymanych katalizatorów wynosiła od 100 do 160 m2/g. Na podstawie analizy rentgenowskiej (XRD) stwierdzono,...

Photocatalytic activity of nitrogen doped TiO2 nanotubes prepared by anodic oxidation: The effect of applied voltage, anodization time and amount of nitrogen dopant
Nitrogen doped TiO2 nanotube arrays were prepared by anodizing Ti foils in an organic electrolyte containing specified amounts of urea as nitrogen precursor. The photocatalytic activity of the samples was evaluated by analyzing the degradation kinetics of phenol in water. The influence of tubes’ length, tubes’ surface morphology and amount of nitrogen in the TiO2 lattice on hydroxyl radical formation efficiency, photocatalytic...

Ordered TiO2 nanotubes: the effect of preparation parameters on the photocatalytic activity in air purification process
Vertically ordered TiO2 nanotube arrays were synthesized by anodic oxidation of titanium foil in glycerol, ethylene glycol and water-based electrolytes. The effect of electrolyte composition, anodization voltage, ultrasonic treatment and calcination time on the morphology of the resulting thin films, as well as on their photocatalytic activity in toluene removal, used as a model volatile organic compound, was investigated. Toluene,...
