Scanning tunneling microscopy studies of Cu islands grown on TiO2(110) demonstrate that these islands disappear from the STM images after exposure to oxygen gas (60-2000 Langmuir). Based on X-ray photoelectron spectroscopy experiments, the disappearance of the Cu islands cannot be explained by the loss of Cu from the surface or by a dramatic change in the electronic properties of the islands. T...

In this data, the properties of transparent TiO2 film for Schottky photodetector are presented for the research article, entitled as "High-performing transparent photodetectors based on Schottky contacts" (Patel et al., 2017) [1]. The transparent photoelectric device was demonstrated by using various Schottky metals, such as Cu, Mo and Ni. This article mainly shows the optical transmittance of ...

Pure TiO2 and Cu–doped containing different amounts of copper ions with anatase/rutile/brookite triphasic structure were successfully synthesized through a simple hydrothermal method. The obtained samples characterized by X–ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM), transmission (TEM), photoelectron spectroscopy (XPS), UV?vis diffuse reflectance (UV-DRS), pho...

The limited antifouling capability of Ti-based components could jeopardize their applications in petroleum engineering. In this work, a Cu-enriched TiO2 coating has been fabricated using an ultrasound-auxiliary micro-arc oxidation (UMAO) method. Cu enrichment affects its morphology, phase component and chemical configuration, leading to the slightly enhanced corrosion resistance relative that f...

This paper presents the features of electrophoretic deposition TiO2, TiO2-$$$MWCNT composites. The influence various dispersant additives in suspension on mobility TiO2 particles and morphology formed layer has been studied. effect modification by Au Cu clusters photocatalytic activity was investigated.

Selective oxidation of benzyl alcohol to benzaldehyde in aqueous solution, under acidic conditions, through the TiO2/Cu(II)/solar UV photocatalytic system, was investigated. Different commercial TiO2 samples were tested. The best result found, in terms of yield, was of 35% for benzaldehyde with respect to the initial benzyl alcohol concentration. During a single run, a partial conversion of ben...

Electron transport in metal conductors with ~5-30 nm width is dominated by surface scattering. In situ transport measurements as a function of surface chemistry demonstrate that the primary parameter determining the surface scattering specularity is the localized surface density of states at the Fermi level N(Ef). In particular, the measured sheet resistance of epitaxial Cu(001) layers with thi...

The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-type Cu(In,Ga)Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin film deposited by atomic layer deposition process at low temperatures shows conformal coverage on the CIGS absorber layer. Solar cells from non-vacuum deposited CIGS absorbers with TiO2 buffer layer result in a high sh...
