Influence of Mn, Cu, and Cd–doping for titanium oxide nanotubes on the photocatalytic activity toward water splitting under visible light irradiation

Tuning the band gap of M-doped titanate nanotubes (M = Fe, Co, Ni, and Cu): an experimental and theoretical study

“…14,18 In this regard, the inuence of different metal cations on the Ti-NT optical properties has been studied previously. 9,[19][20][21][22] Lee and Zaki studied the inuence of cations with different valences (Mg 2+ , Ca 2+ , Zn 2+ , K + , Cr 3+ , Ce 3+ , Ce 4+ , Mo 5+ , and La 3+ ). These results showed that the semiconductor band gaps could be modied in the range of 2.02-2.8 eV.…”

Acceleration of ammonium phosphate hydrolysis using TiO2 microspheres as a catalyst for hydrogen production

“…[13][14][15] On the other hand, titanium dioxide (titania) is widely used as an effective photocatalyst due to its good photocatalytic and optical properties. 13,16 Despite the wide band gap range of the different phases of titania, its efficiency is still limited because of the fast recombination and poor absorption of visible light (solar radiation contains 55.4% visible radiation). In addition, different morphological structures, such as nanoparticles, 17 nanobers, 18 nanowires, 19 nanotubes 20 and nanospheres, 21 can be easily attained for titanium dioxide.…”

Nanocomposite of TiO2 @ Ni- or Co-doped graphene oxide for efficient photocatalytic water splitting

“…Basically, the photocatalytic water splitting reaction produces one-third oxygen gas and two-thirds hydrogen gas. M. S. Mahmoud et al [11] indicated experimentally that the hydrogen gas comes from water and ethanol. Moreover, they proved experimentally that CO 2 gas is not generated by collecting the evolved gases above Ca(OH) 2 solution, where no turbidity is observed.…”
