“…The evolution of these peaks depends on the oxygen partial pressure during plasma deposition, as shown in Fig. 2 18,19 In some cases the films are not conducting enough, which is why the electron flood gun is used during the XPS analysis.…”

“…Note, however, that the surface defects can cause band bending and a rigid shift of the whole spectrum. This probably accounts for the scatter in experimental peak positions [2,3,52,[185][186][187][188]. Only one symmetric signal was measured for Ti 2p 3/2 up to 800 K for nanowires and nanotubes [183].…”

Titanates are salts of polytitanic acid that can be synthesized as nanostructures in a great variety concerning crystallinity, morphology, size, metal content and surface chemistry.Titanate nanotubes (open-ended hollow cylinders measuring up to 200 nm in length and 15 nm in outer diameter) and nanowires (solid, elongated rectangular blocks with length up to 1500 nm and 30-60 nm diameter) are the most widespread representatives of the titanate nanomaterial family. This review covers the properties and applications of these two materials from the surface science point of view. Dielectric, vibrational, electron and X-ray spectroscopic results are comprehensively discussed first, then surface modification methods including covalent functionalization, ion exchange and metal loading are covered. The versatile surface chemistry of onedimensional titanates renders them excellent candidates for heterogeneous catalytic, photocatalytic, photovoltaic and energy storage applications, therefore, these fields are also reviewed.

“…These O-vacancy defects are revealed with characteristic features in the Ti 2p and O 1s regions as well as in the valence band [74,90]. Figure 7 shows (a) Ti 2p 3/2 and (b) O 1s XPS spectra for the defective TiO 2 (110) ) [90,91]. In the O 1s region, a small component is observed at about 1 eV higher binding energy than the lattice oxygen peak at 530.5 eV.…”

X-ray photoelectron spectroscopy (XPS) is a powerful tool for surface and interface analysis, providing the elemental composition of surfaces and the local chemical environment of adsorbed species. Conventional XPS experiments have been limited to ultrahigh vacuum (UHV) conditions due to a short mean free path of electrons in a gas phase. The recent advances in instrumentation coupled with third-generation synchrotron radiation sources enables in-situ XPS measurements at pressures above 5 Torr. In this review, we describe the basic design of the ambient pressure XPS setup that combines differential pumping with an electrostatic focusing. We present examples of the application of in-situ XPS to studies of water adsorption on the surface of metals and oxides including Cu(110), Cu(111), TiO 2 (110) under environmental conditions of water vapor pressure. On all these surfaces we observe a general trend where hydroxyl groups form first, followed by molecular water adsorption. The importance of surface OH groups and their hydrogen bonding to water molecules in water adsorption on surfaces is discussed in detail.
