Highly efficient visible light TiO2 photocatalyst prepared by sol–gel method at temperatures lower than 300°C

Enhanced visible-light photocatalytic activity of active Al2O3/g-C3N4 heterojunctions synthesized via surface hydroxyl modification

“…As can be seen from Fig. 6b, the only one C1s peak of pure Al 2 O 3 at 284.6 eV is ascribed to adventitious carbon contamination [45,46]. As for g-C 3 N 4 , in addition to the polluted carbon peak at 284.9 eV, there is another peak at 287.9 eV, which is attributed to carbon atoms bonded to three nitrogen atoms in the g-C 3 N 4 lattice [47,48].…”

Photocatalytic degradation of monocrotophos and chlorpyrifos in aqueous solution using TiO2 under UV radiation

“…The obtained solution was sealed and stirring was continued for another 30 min at room temperature. The resultant gel was aged at room temperature for 24 h and dried in an oven at 100 • C for 36 h. After grinding, the gel was heat-treated in a furnace at 300 • C for 3 h and white crystalline TiO 2 nanoparticles were obtained at the end of the process [18,20].…”

“…The bands at 2930 cm −1 , 2855 cm −1 and 1381 cm −1 correspond to the stretching and bending modes of C H bonds, which come from the residual butyl group in the prepared TiO 2 . The band at 482 cm −1 corresponds to the Ti O bending mode of TiO 2 [20].…”

Novel silver-doped NiTiO3: auto-combustion synthesis, characterization and photovoltaic measurements

“…23 Furthermore, the absorption peaks at 536 and 685 cm -1 correspond to the Ti-O bending mode of TiO 2 . 24 Moreover, the band at 446 cm -1 can be assigned to the absorption band of Ni-O, which confirms the formation of NiTiO 3 .…”
