Degradation of propanol diluted in water under visible light irradiation using metal ion-implanted titanium dioxide photocatalysts

A review on the visible light active titanium dioxide photocatalysts for environmental applications

“…If the initial 29 photoexcitation process occurs in an adsorbate molecule, which then interacts with the 30 ground state of the catalyst substrate, the process is referred to as a "catalyzed 31 photoreaction", if, on the other hand, the initial photoexcitation takes place in the catalyst 32 substrate and the photoexcited catalyst then interacts with the ground state adsorbate 33 molecule, the process is a "sensitized photoreaction". In most cases, heterogeneous 34 photocatalysis refers to semiconductor photocatalysis or semiconductor-sensitized 35 photoreactions [23]. 36 37…”

Nitrogen-doped titanium dioxide photocatalysts for visible response prepared by using organic compounds

“…Therefore, it is of great interest to find ways to extend the absorption wavelength range of TiO 2 to visible region without the decrease of photocatalytic activity [5][6][7][8][9][10]. Several groups have been succeeded in doping transition metals into TiO 2 photocatalyst to obtain photo-response at visible light [6][7][8]. Recently, TiO 2 doped with S atom [9,10] and F atom [11] have been reported.…”

Comparative assessment of the efficiency of Fe-doped TiO2prepared by two doping methods and photocatalytic degradation of phenol in domestic water suspensions

“…In addition, the effect of dopant has a primary role in extending the light absorption and conversion capacities of TiO 2 to the visible light. A wide range of metal ions have been used to prepare the chemically metal-doped TiO 2 [2][3][4][5][6][7][8], the physically metalimplanted TiO 2 [9][10][11], and the TiO 2 -based binary oxide [4]. Their effects on the properties of the doped samples have been reported.…”
