“…The position of this peak varied very little across the rows and columns. Also, the binding energy of the Sn 3d 5/2 peak was seen at 486.9 eV, matching literature values for Sn 4+ . Again, the peak position hardly varied across and along the positions analyzed.…”

Combinatorial atmospheric pressure (cAP)CVD is used to deposit a film of graded composition from mainly TiO 2 to TiO 2 /SnO 2 to mainly SnO 2 . This is the first cAPCVD study of a TiO 2 /SnO 2 system. The thin film is characterized using a range of techniques such as X-ray diffraction (XRD), wavelength dispersive X-ray (WDX) spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and ultra violet-visible (UV-vis) spectroscopy. It is found that, at various positions on the film, there are intimate compositions of TiO 2 and SnO 2 . The photocatalytic activity is examined via the degradation of a Resazurin-based 'intelligent ink' under 365 nm wavelength irradiation. The change in the concentration of the dye can be monitored by digital imaging alone. The results show how TiO 2 -rich regions are photocatalytically active, producing a maximum formal quantum yield of 3.32 Â 10 À4 molecules per absorbed photon. The sheet resistance is determined using a four-point probe via the van der Pauw method. The conductivity is highest in the SnO 2 -rich and thicker regions of the film, however some of the intimate composite regions of TiO 2 /SnO 2 show both conductivity and photocatalytic activity.

“…The ratio between metallic (0) and oxidized (+II) forms of Pt was about 4:1 for all the synthesized nanoparticles, presumably due to some interaction with atmospheric oxygen. The Sn3d signal exhibits two well-defined isolated peaks; peak (1) located at approximately 487 eV can be attributed to the Sn3d 5/2 contribution and peak (2) at 496 eV to the Sn3d 3/2 contribution of Sn II [35,36]. It must be pointed out that discrimination between signals of Sn II and Sn IV is often difficult to carry out.…”

“…Fig. 12c, displays a doublet that corresponds to the Sn 3d 5/2 and Sn 3d 3/2 transitions at low and high binding energies, respectively [41]. The reported binding energies of SnO and SnO 2 are 486.5 and 487.5 eV, respectively [42].…”
