Cooperation among N, F and Fe in tri-doped TiO2 photocatalyst

Morphological Effect in Photocatalytic Degradation of Direct Blue over Mesoporous TiO2 catalysts

“…According to our previous study, [32] the kinetics of photocatalytic degradation under UV was found following a pseudosecond-order reaction kinetic model with high regression coefficients (R 2 ). And the kinetic parameters for the TiO 2 with different morphologies were summarized in Table 2.…”

Synthesis of renewable C–C cyclic oxygenated compounds dedicated for high-density biofuels from biomass-derived cyclopentanone

“…Notably, a strong peak at 3695.63 cm À1 was assigned to the O-H stretching vibration for the crystal structure of Mg(OH) 2 , implying its successful synthesis. 52 Moreover, the asymmetric stretching vibration (at 1487 cm À1 and 1429 cm À1 ), the symmetric vibration (at 1117 cm À1 ) and the bending vibration (at around 885 cm À1 to 595 cm À1 ) of CO 3 2À were clearly observed for the MgCO 3 and 4MgCO 3 ÁMg(OH) 2 Á4H 2 O. 53 Altogether, the above results distinctly demonstrated that Mg(OH) 2 , MgCO 3 and 4MgCO 3 ÁMg(OH) 2 Á4H 2 O catalysts were prepared successfully.…”

Synthesis of nitrogen and terbium co-doped TiO2nanocrystals with enhanced photocatalytic activity for AO7 degradation under visible-light radiation

“…So far, a variety of co-doping systems have been reported. [15][16][17][18][19] For instance, Yu et al have reported a Sn/N co-doped system, which exhibited improved activity in the photocatalytic degradation of rhodamine B and acetone; 15 Liu et al reported a Ce/N co-doped system, which exhibited improved activity in the photocatalytic treatment of antibiotics; 16 and Ashjari et al reported an Fe/S co-doped system, which exhibited improved activity in the photocatalytic decomposition of NH 3 . 17 Among the choices of metals available for TiO 2 doping, lanthanide metals are of particular interest since doping of TiO 2 with lanthanide metals gives additional benefits apart from those mentioned above.…”
