Gas phase synthesis of SnOx nanoparticles and characterization

Nopol production over Sn-MCM-41 synthesized by different procedures – Solvent effects

“…The values reported for Sn 3d 5/2 and Sn 3d 3/2 transitions for tin hydroxide, Sn 6 O 4 (OH) 4 with Sn(II) species, are 486.7 and 495.1 eV, respectively [43]. For SnO x nanoparticles, signals at 487 and 495.5 eV have been observed [44]. By XPS and Auger spectroscopy, Jiménez et al found positive binding energy shifts of around 1 eV in the Sn3d transitions of very low SnO and SnO 2 coverage over silica [45].…”

Aluminum Nanoparticle Production by Acetonitrile-Assisted Milling: Effects of Liquid- vs Vapor-Phase Milling and of Milling Method on Particle Size and Surface Chemistry

“…The C 1s spectrum shows a peak at ∼285 eV with a substantial tail to higher binding energy, fit by a second component peaking near 287 eV. The fact that the sample was exposed to acetonitrile and other solvent vapors in the glovebox is expected to lead to adventitious carbon signal, which is often in the 285 eV range for sp 2 -hybridized carbon ,− but also for C bound to N (285–288 eV) or C bound to O (∼286.5). The important observation is that there is no significant signal at the energy expected for aluminum carbide (282.4 eV).…”

Study of blueshift of optical band gap in stannic oxide nanosheets by an uncharged surfactant mediated alcohothermal process

“…[3,4,[9][10]. The synthesis of different SnO 2 nanostructures by using various methods, such as gas phase condensation method, pulsed laser deposition, spray pyrolysis, and chemical bath deposition method has been reported in the literature [11,12]. These methods are complicated, and also very difficult to produce 2-D SnO 2 nanostructures.…”
