Dependence of photocatalysis on electron trapping in Ag-doped flowerlike rutile-phase TiO2 film by facile hydrothermal method

Role of Oil Palm Empty Fruit Bunch-Derived Cellulose in Improving the Sonocatalytic Activity of Silver-Doped Titanium Dioxide

“…Among these approaches, silver (Ag) doping was chosen in this study as Ag can serve as a prominent plasmonic material for sensitizing TiO 2 . Moreover, Ag is generally cheap and exhibits low toxicity and high antibacterial ability than compared to gold and platinum [ 14 ]. The incorporation of an appropriate amount of Ag can reduce the band gap energy of TiO 2 and inhibit the recombination of electron-hole pairs by trapping the electrons due to the prominent surface plasmon resonance [ 15 ].…”

Characterization of Pure Rutile Titania Nanoparticle Prepared by Feasible Method for Coatings and Visible Light-Driven Dye Removal Application

“…The XRD pattern obtained was in good agreement with the JCPDS file. Thus, the conditions of hydrothermal reactions followed in the present study were solely responsible for the formation of high pure phase formation [16,17]. Figure 1a shows the XRD pattern for rutile TiO 2 and that the pattern obtained for 4T possessed peaks corresponding to the planes of TiO 2 at 2θ = 27.4 (110), 36.0 (101), 39.1 (200), 41.2 (111), 44.0 (210), 54.3 (211), 56.6 (220), 62.7 (002), 64.0 (310) and 69.0 (301), respectively [18][19][20].…”

“…The heat temperature (Tc) reliance of SnO 2 -TiO 2 nanocrystals showed enhanced photocatalytic activity towards the ethanol to acetaldehyde oxidation reaction processes. The mechanism of higher efficiency due to the high electron mobility in the SnO 2 NRs and the existence of proficient electron transfer band levels were found [16]. Hence, in the present study, pure rutile TiO 2 was synthesized using various concentrations of nitric acid treatment followed by a hydrothermal process.…”

“…Recently, rutile-phase titania film exhibited a flower-like structure with unprotected (110) and (111) facets; this was prepared with the aid of hydrothermal techniques, in the absence of additive agents, with different additions of silver from 0.5 to 2 wt.% [14]. The flower-like features enhanced the active surface area of the titanium oxide film [14][15][16]. Furthermore, 1 wt.% silver particle doping caused the maximum methylene blue degradation to occur, which was 20% greater than that of the undoped titanium oxide film.…”

Photoreduction properties of novel Z-scheme structured Sr0.8La0.2(Ti1−δ4+Tiδ3+)O3/Bi2MoO6 composites for the removal of Cr(vi)

“… 39 ) and 463.92 eV, 40 attributed to Ti 4+ 2p 3/2 and Ti 4+ 2p 1/2 , respectively, in SrTiO 3 , while there are higher binding energies of 458.36 eV and 464.33 eV for Ti 4+ 2p 3/2 and Ti 4+ 2p 1/2 in the LSTBM7, respectively. Furthermore, the peaks located at 457.30 eV and 462.70 eV of LSTO correspond to Ti 3+ 2p 3/2 and Ti 3+ 2p 1/2 , 41 respectively. So, O v -s may have been introduced in the LSTO by mixed-valence of titanium (Ti 4+ /Ti 3+ ) to balance the charge of the compound.…”
