Multi-layer three-dimensionally ordered Bismuth trioxide/Titanium dioxide nanocomposite: Synthesis and enhanced photocatalytic activity

Enhanced photocatalytic, electrochemical and photoelectrochemical properties of TiO2 nanotubes arrays modified with Cu, AgCu and Bi nanoparticles obtained via radiolytic reduction

“…However, in most research, the properties of Bi-doped TiO 2 photocatalysts (mixed Bi-Ti-oxide phases, Bi 2 O 3 -TiO 2 composites) obtained via sol-gel [63], [64], [65], [66] and hydrothermal [67] methods were examined. There is also an example of TiO 2 nanotubes ordered arrays modified with Bi 2 O 3 using dip coating method, exhibiting high photoelectrocatalytic properties [68] and an example of Bi-doped TiO 2 NTs (used for energy storage) obtained via direct anodization of Bi-Ti alloy.…”

Fabrication of α-Fe 2 O 3 /In 2 O 3 composite hollow microspheres: A novel hybrid photocatalyst for toluene degradation under visible light

“…Moreover, these catalytic materials were extremely stable and no deactivation was found during the prolonged reaction process [18][19][20]. Nonetheless, because of their large band-gap energies (4.95 eV for β-Ga 2 O 3 [21], 3.70 eV for InOOH [19], and 5.15 eV for In(OH) 3 [20], respectively), the excitation of their photocatalytic capability requires UV light (400 nm > λ), which accounts for less than 4% of the entire solar energy spectrum reaching the surface of the earth [22][23][24]. Thus, this disadvantage significantly hinders the practical applications.…”

“…X-ray Photoelectron Spectroscopy analysisXPS was employed to further investigate the chemical valence states of the as-prepared samples and the interactions between the αHerein, a minor amount of contaminated carbon can be attributed to either the hydrocarbon related to the instrument itself or the organic impurities removed incompletely[42,43]. The surface In, Fe, and O were further studied by high-resolution XPS profiles.Fig.…”

Multi-layer and open three-dimensionally ordered macroporous TiO2–ZrO2 composite: diversified design and the comparison of multiple mode photocatalytic performance

“…The results are shown in Fig. 8(f), which illustrates that the existence of capturing agents reduces the photocatalytic activity of 3DOM TiO 2 -ZrO 2 samples in the UV photocatalytic degradation progress of MO to a certain degree; therefore, the active species •OH and O 2 • − do indeed exist in the photocatalytic system [11,49,50]. In addition to capture experiments, there are also a lot of literature reports on the successful detection of •OH active groups by the photoluminescence technology [51,52].…”
