Photocatalytic degradation of gas pollutants on self-assembled titania nanotubes

Ordered TiO2 nanotubes: The effect of preparation parameters on the photocatalytic activity in air purification process

“…However, there is only a few reports about using anodized, ordered TNTs arrays as a photocatalytic material for air treatment. TiO 2 NTs were used to remove acetalaldehyde [26], toluene and benzene [27] and NO x oxidation [28] in the gas phase.…”

Enhanced photocatalytic activity for titanium dioxide by co-modification with copper and iron

“…The high costs associated with current technologies of water purification have stimulated efforts to develop effective but also inexpensive technologies for this purpose. Besides well-established techniques such as electrochemical techniques, adsorption, biological treatment and oxidation, photocatalysis is considered to be a 'green' method for water decontamination, as it can lead to fast and complete mineralization of contaminants, without leaving harmful intermediates [1][2][3][4][5][6]. Various heterogeneous photocatalysts offer a means of destroying most organic pollutants present in water at low concentrations.…”

ZnO and TiO2 1D nanostructures for photocatalytic applications

“…In the presence of a photocatalyst, organic contaminants can be oxidized directly by a photogenerated hole or indirectly via reaction with reactive oxygen species (ROS), such as hydroxyl radical OH • , produced in the solution [1]. TiO 2 is a widely used photocatalyst material [1][2][3][4][5][6][7]. It exhibits photocatalytic activity under UV illumination [1].…”

“…Photocatalysis has been intensively investigated in recent years [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In a photocatalytic process, electron-hole pairs are generated under illumination, followed by oxidation and/or reduction reactions at the surface of the photocatalyst [1].…”
