A Novel Method for Preparing Ordered SnO2/TiO2 Alternate Nanoparticulate Films

Structural and optical properties of SnO2 films grown on α-Al2O3(0001) by MOCVD

“…5a and b show tin and oxygen peaks, respectively. The tin core levels Sn (3d5/2) and Sn (3d3/2) observed at 486.3 and 494.8 eV, respectively, with a peak-to-peak separation of 8.5 eV confirm the formation of SnO 2 [14]. The O (1s) peak is located at 530.4 eV, which is attributed to lattice oxygen in the SnO 2 crystal structure.…”

Novel synthesis of well-dispersed crystalline SnO2 nanoparticles by water-in-oil microemulsion-assisted hydrothermal process

“…In Fig. 6c, the characteristic peak of O1s is at 530.9 eV, which can be attributed to the lattice oxygen in SnO 2 [22].…”

“…6b, the peaks at the binding energies of 486.6 and 495.0 eV correspond to Sn3d 5/2 and Sn3d 3/2 , respectively [22]. The peak of Sn3d 5/2 shows only one symmetric component and has no shoulder peak, which illustrates that the tin-containing compound is SnO 2 [22]. In Fig.…”

“…6 shows the XPS spectra of SnO 2 nanoparticles obtained at 130 • C for 15 h. It can be seen that in the whole region of 0-900 eV, the characteristic peaks of Sn3d, Sn3p, and O1s are presented (shown in Fig. 6a) [22,23]. As shown in Fig.…”

Fabrication and Photocatalytic Activity of TiO₂/MoO₃ Particulate Films

“…Another way to promote photocatalytic activity in semiconductors is to retard the recombination of photoexcited electrons and positive holes by producing charge separation 7,[23][24][25] . To achieve this, it is necessary to control the orientation of the particles or to fabricate a two-dimensional heterostructure of particles on a substrate.…”
