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 ...

实验信息 无 XPS 光谱解读 钛金属的 Ti2p 峰形不对称。 TiO2 的峰形对称，TiN 的峰形复杂，包括卫星特征峰。 Ti2p 峰具有明显的自旋轨道分裂峰 (Δ 金属 =6.1 eV)。 不同化学状态的分裂值不同 (Δ 氮化物 =6.0 eV，Δ 氧化物 =5.7 eV)。

1998年11月1日 · Thin TiO x films deposited on quartz substrates have been studied using XPS and X-ray diffraction (XRD). It is found that different titanium oxide species coexist in the films. The dependencies of these species on the calcination temperature and …

2016年8月30日 · Variation in surface species viz. Ti3+, Ti4+, O2−, oxygen vacancies, OH group and optical properties was studied using X-ray photon spectroscopy (XPS) and UV-Vis spectroscopy.

XPS Spectra Titanium (Ti) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.

Download scientific diagram | O 1s XPS spectra of original TiO2 and amorphous hydroxylated TiO2 prepared through ultrasonication for different hours. from publication: Black Hydroxylated...

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...

Ti 2p and Ti 3p X-ray photoelectron spectra (XPS) were taken for TiO, SrTiO and BaTiO single crystals fractured in an electron spectrometer. The inelastic scattering energy loss parts were removed from the observed Ti core level XPS by a deconvolution method using O 1s spectra as a response function.

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.

TiO 2 -SiO 2中 的钛价态 XPS对混合氧化物进行了研究，其光谱报告了高二氧化硅浓度时存在Ti 2+ 和Ti 3+ 阳离子，表明形成了氧空位。 对于亚甲基蓝（MB）的光降解，已经评估了制备的材料的光催化活性。 混合氧化物通过紫外光源活化，并通过紫外可见光谱仪监测甲基溴的浓度。 与市售的TiO 2 Degussa P25相比，合成的TiO 2 -SiO 2的 MB去除效率明显更高。 在本文中，我们观察到钛的三个价态：TiO 2 -SiO 2 40％中的Ti 4+，Ti 3+ 和Ti 2+。 尚未报告此问题。 XPS分析表 …
