Enhanced Photoelectrocatalytic and Photoelectrochemical Properties by High-Reactive TiO 2 /SrTiO 3 Hetero-Structured Nanotubes with dominant {001} Facet of Anatase TiO 2

Heterojunction of SrTiO3/TiO2 nanotubes with dominant (001) facets: Synthesis, formation mechanism and photoelectrochemical properties

“…5d located at 529.5 eV and 531.7 eV. [27] The first peak is corresponded to the O atom bound to the metals such as Ti and Sr, while the latter peak is ascribed to the surface hydroxyl specie [15,17]. The above XPS analysis further indicates that TiO 2 was partly converted to SrTiO 3 , which is consistent with the result of the XRD analysis.…”

“…Previous reports on SrTiO 3 /TiO 2 heterojunction have mainly focused on improving synthetic routes to enhance photocatalytic activities. However, the photoelectric performances, especially semiconductor characteristics of the heterojunction interface have rarely been reported up to now [15][16][17] and are still not fully clear.…”

Enhanced properties for visible-light-driven photocatalysis of Ag nanoparticle modified Bi2MoO6 nanoplates

“…The hetero-structured semiconducting nanomaterials are one way to improve the photocatalytic activity of visible light driven photocatalysts due to the photo-generated charged carriers transfer, separation distance, recombination rate, and surface plasmon resonance (SPR), leading to the enhancement of photocatalytic activity of the visible light driven photocatalysts [15][16][17] [19,20], BiOCl/Bi 2 MoO 6 [21,22], TiO 2 /Bi 2 MoO 6 [23,24] and Bi 2 MoO 6 /BiPO 4 [25]. Moreover, the incorporation of metal nanocrystals/semiconductors such as Ag/ZnO [26], Ag/TiO2 [27], Ag/AgCl [28] and Ag/MoO 3 [29] has shown great promise for rising visible light photocatalytic activities due to the localized surface plasmon resonance (LSPR) [26,27].…”

Sequential Processes to Produce N-TiO2Films Through Rf Plasmas

“…Later is consistent with the results of XRD. The E 1g peak is associated with the symmetric stretching vibration of O-Ti-O in TiO 2 , the B 1g peak is due to the symmetric bending vibration of O-Ti-O [34], and the A 1g peak is the result of antisymmetric bending vibration of O-Ti-O [35]. Considering the proposed by Fang Tian et al [34], the ratio of the Raman vibrational modes intensities between E 1g and A 1g for TiO 2 and N-TiO 2 films, the percentage are approximately of 11%, i.e., the symmetric and antisymmetric vibrations remain without perceptible change.…”
