2017年4月1日 · The X-ray photoelectron spectroscopy (XPS) qualification of core-levels and valence bands and Density-Functional Theory (DFT) calculations were employed in order to study the yielded electronic structure of Pb-ion modulated TiO 2 host-matrices.

2001年4月3日 · The surfaces of hydrophilic (P25) and hydrophobic (T805) TiO 2 particles were characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) to gain a better understanding of the adsorption mechanism of OLOA 370 (polybutene-succinimide pentamine) on TiO 2 particles dispersed in styrene monomer prior ...

2017年2月27日 · Consecutive eight study phases under the successive presence and absence of UV irradiation, water vapor, and oxygen were conducted to characterize surface changes in the photocatalytic TiO 2...

核能级和价带的 X 射线光电子能谱 (XPS) 鉴定和密度泛函理论 (DFT) 计算被用来研究 Pb 离子调制的 TiO2 基质的电子结构。 XPS 和 DFT 的组合分析与在 TiO2:Pb 的本体形态中注入刺激的 PbO 样结构的外观一致，而在薄膜形态中，类 PbO2 结构变得占主导地位，基本上有助于 ...

Ti3+ self-doping black TiO2 nanotube arrays (Ti/B-TiO2-NTs) as an interlayer were used for preparing a novel PbO2 electrode via an electrochemical reduction technology, and a sodium...

The O 1 s XPS spectra in Fig. 3 demonstrate similar shapes of origi- nal TiO 2 and ultrasonic treated TiO 2 for different hours, and the single O 1 s peak in each spectrum can be divided into...

Download scientific diagram | XPS Pb 4f core-level spectra of Pb-implanted TiO2 host-matrices in the bulk and thin-film morphologies. The appropriate -PbO (Pb 2+ ), -PbO2 (Pb 4+ ) and...

1996年7月1日 · A stochiometric TiO 2 surface can reproducibly be prepared through sputtering and annealing in oxygen (2 × 10 −4 Pa, 900 K). Our XPS core level spectra are measured from a bulk-reduced titanium dioxide (rutile) (110) surface using a VSW hemispherical analyzer.

1999年2月1日 · Valence state analysis by XPS confirms the incorporation of Pb into the TiO 2 lattice as a tetravalent ion and therefore the formation of the material Pb x Ti 1−x O 2.

2024年1月1日 · This work systematically and elegantly employs an argon ion (Ar +) beam to create oxygen vacancies in TiO 2 mesoporous film at different time of radiation exposure. Survey spectra acquired from XPS compositionally indicates the presence of oxygen (O 1s), titanium (Ti 2p) and carbon (C 1s).
