Amorphous TiO2 beats P25 in visible light photo-catalytic performance due to both total-internal-reflection boosted solar photothermal conversion and negative temperature coefficient of the forbidden bandwidth

Electrochemical and Photoelectrochemical Detection of Hydrogen Peroxide Using Cu2O/Cu Nanowires Decorated with TiO2−x Deriving from MXenes

“…Hence, MXene-derived TiO 2 may have better performance than the commercial P25, which is consisted of anatase (80%) and rutile (20%). 38 The XPS surface scan spectrum of TiO 2−x / Cu 2 O/Cu-NWs shown in Figure 3b confirms the presence of Cu, O, and Ti elements. Figure 3c−e shows the highresolution spectra of Ti 2p, Cu 2p, and O 1s, respectively.…”

“…The anatase TiO 2 in the TiO 2– x /Cu 2 O/Cu-NWs is similar to the in situ generated TiO 2 from Ti 3 C 2 MXene, which is normally dominated by the thermodynamically stable {101} facets due to their lower surface energy (0.44 J·m –2 ), − leading to better photocatalytic activity than rutile. Hence, MXene-derived TiO 2 may have better performance than the commercial P25, which is consisted of anatase (80%) and rutile (20%) . The XPS surface scan spectrum of TiO 2– x /Cu 2 O/Cu-NWs shown in Figure b confirms the presence of Cu, O, and Ti elements.…”

NOx degradation ability of S-g-C3N4/MgAl-CLDH nanocomposite and its potential application in cement-based materials

“…It has however drawbacks such as large band gap width (3.2 eV), high rate of recombination of photogenerated electron–hole pairs, low utilization of visible light and susceptibility to aggregation. 5 Compared to TiO 2 , a new semiconductor photocatalytic material, graphite carbon nitride (g-C 3 N 4 ), has a smaller band gap width (2.7 eV), a wider range of response to visible light and a lower cost. 6 It is reported that g-C 3 N 4 can be stimulated by ultraviolet-visible (UV-vis) light and has been utilized in various depollution fields such as degradation of organic pollutants and the mitigation of air pollution.…”

Localized surface plasmon resonance effect enhanced Cu/TiO2 core–shell catalyst for boosting CO2 hydrogenation reaction

“…Recently, Yang et al prepared SiO 2 @TiO 2 core–shell catalysts and showed that the total reflection of light between SiO 2 and TiO 2 significantly improved the light absorption capacity and photo-to-thermal conversion of the material. 32 Cao et al prepared black N–TiO 2− x hollow spheres through the evaporation-induced self-assembly (EISA) process. A large specific surface area, narrow bandgap, and enhanced light absorption properties were considered to be the main factors for enhanced activity.…”
