Photocatalytic Decomposition of Acetaldehyde under Visible Light Irradiation over La3+ and N Co-doped TiO2

Abstract

La3+ and N co-doped TiO2, which contained paramagnetic N species, decomposed acetaldehyde under visible light irradiation. The number of the paramagnetic N species seemed to control the absorption of visible light and the activity.

Cr/S/TiO2-loaded hollow glass microspheres as an efficient and recyclable catalyst for the photocatalytic degradation of indigo carmine under visible light

“…[23][24][25] Figure 4 presents the UV-Vis diffuse reflection absorption spectra of TiO 2 , Cr/S/TiO 2, and Cr/S/TiO 2 -HGM. The absorption wavelength of pure TiO 2 is less than 400 nm, and bulk TiO 2 is a wide band gap semiconductor with a band gap of 3.2 eV (387 nm) for anatase.…”

Characterization and activity of visible-light-driven TiO2 photocatalyst codoped with nitrogen and cerium

“…It was reported that nitrogen and lanthanum codoped TiO 2 nanoparticles showed a superior photocatalytic activity on degradation of methyl orange under visible light irradiation compared to N-doped or La-doped TiO 2 [10,11]. The N-F codoped TiO 2 Doping TiO 2 with lanthanide element has attracted increasing attention due to their special 4f electron configuration [13][14][15][16][17][18][19][20][21][22].…”

The Synergistic Effect of Nitrogen and Ni2O3over TiO2Photocatalyst in the Degradation of 2,4,6-Trichlorophenol Under Visible Light

“…Sakatani et al 15 reported that the N and La codoped TiO 2 photocatalyst which prepared by means of polymerized method could degrade acetaldehyde under visible light irradiation. Zhao et al 16 reported that the spectral response and photocatalytic efficiency could be improved by co-doping with nonmetal boron and the metal oxide Ni 2 O 3 .…”
