Modification of 1D TiO₂ nanowires with GaO_xN_y by atomic layer deposition for TiO₂@GaO_xN_y core–shell nanowires with enhanced photoelectrochemical performance

Abstract

The excellent PEC activity of TiO2 nanowires with GaOxNy results from the enhanced light absorption, favourable band alignment, and high reducibility.

1D/2D/0D Mixed-Dimensional TiO2/ZnO/Ag Core–Shell Nanowires for High-Performance UV–Vis Photoelectrochemical Photodetectors

“…In addition, the TiO 2 /ZnO/Ag NWs strongly absorbed both UV and visible light due to the superposition of the charge carrier absorption spectra of the heterostructure formed between TiO 2 NWs, ZnO NWs, and Ag NPs. The bandgap ( E g ) was calculated from the plot of a transformed Kubelka–Munk function, as shown in Figure b. The bandgaps of TiO 2 , TiO 2 /ZnO, and TiO 2 /ZnO/Ag NWs were 3.01, 2.90, and 2.74 eV, respectively.…”

Fabrication of brookite@anatase heterojunction TiO2via phase transformation from metal organic frameworks for enhanced photocatalytic hydrogen evolution and TCH degradation

“…50,51 respectively, while the characteristic absorption peaks at about 538, 635 and 747 cm −1 can be attributed to the stretching vibration of Ti-O bonds (Ti-O-C/Ti-O-Ti) in the metal-organic framework of MIL-125(Ti). 41,52 It is worth…”

Dual promotional effect of CuxO clusters grown with atomic layer deposition on TiO2 for photocatalytic hydrogen production

“…Hubbard U corrections were implemented, with U(Ti) = 4.5 eV, to consistently describe the partially filled 3d state in reduced Ti 3+ . 46,47 Cation oxidation states were determined from Bader charge analysis and spin magnetizations.…”

“…All calculations were spin-polarized, and there were no symmetry constraints applied. Hubbard U corrections were implemented, with U(Ti) = 4.5 eV, to consistently describe the partially filled 3d state in reduced Ti 3+ 46,47. Cation oxidation states were determined from Bader charge analysis and spin magnetizations.To model the different surface modifications, the following models are used: Cu 20 cluster on anatase (101), Cu 10 O 10 on anatase (101), 2 Cu 10 nanoclusters on anatase (101), and reduced CuO nanoclusters (by removing oxygen from CuO).…”
