Preparation of carbon-sensitized and Fe–Er codoped TiO2 with response surface methodology for bisphenol A photocatalytic degradation under visible-light irradiation

Synthesis of rare earth doped TiO2nanorods as photocatalysts for lignin degradation

“…In order to enhance the interfacial charge-transfer efficiency and utilize a wider spectral range of solar energy, the TiO 2 catalyst has been modified by ion doping 19,20 and manipulating the nanomaterial composition. 21,22 Rare earth (RE) ion dopants, such as Ce, 23 La, 24 Er 25 and Pr, 26 have shown unique enhancement effects, resulting from the orbital hybridization of 4f electrons. Positive effects of 4f electron orbital hybridization on the photocatalytic activities of TiO 2 were reported previously.…”

Enhanced solar photocatalytic activity of Er3+:YAlO3-loaded BiPO4 composite

“…First of all, it was reported that, under the excitation lights of 652.2 and 657.8 nm, Er 3+ :YAlO 3 as upconversion luminescence agent could emit lights around 318.7 and 320.1 nm [21,22,29], which is matched well with the absorption edge of BiPO 4 , and hence accelerated the reaction. Therefore, the entire Er 3+ :YAlO 3 loaded BiPO 4 works under solar light as shown in Fig.…”

An experimental design approach for hydrothermal synthesis of NaYF4: Yb3+, Tm3+ upconversion microcrystal: UV emission optimization

“…Each experiment consisted of 9 runs. Design expert software was used for the analysis of experimental data [18][19][20][21].…”
