X-ray photoelectron spectroscopy (XPS) analysis was performed on TiCl4/MgCl2/EB (ethyl benzoate) catalysts, TiCl4/MgCl2 internal donor free catalysts and TiCl4路EB complex to elucidate the effect of EB on electronic state of Ti species in TiCl4/MgCl2/ EB catalysts. Combined with FTIR analysis...
Microcrystalline cellulose samples with different crystallization index(Icr) were obtained by treatment with ionic liquids(ILs) 1-n-butyl-3-methylimidazolium chloride(Cl).The C1s spectra and O1s spectra from X-ray photoelectron spectroscopy(XPS)were adopted firstly to analyze the changes of crystallizati...
X-ray photoelectron spectroscopy (XPS or ESCA), is an analytical technique that depends upon the measurement of the energies of photoelectrons that are emitted from atoms when they are irradiated by soft X-ray photons (1 – 2 keV). When used to study solids, XPS analysis has a number of...
The X-ray photoelectron spectroscopic characterizations of Pt nanoparticles evaporated onto untreated and Ar + -treated highly oriented pyrolytic graphite surfaces, with, respectively, low and high surface defect densities have been studied using multicomponent analysis with symmetric line shapes: each Pt4f...

X射线光电子能谱(X-RayPhotoelectronSpectroscopy,简称XPS)分析是利用X射线照射 样品,使样品中原子的电子受激发射,然后测量这些电子的能量分布,从而获得所需的信息。 由于通常使用的X射线(AlKα,MgKα等)是软X射线,所以X射线光电子能谱只能分析来 自样品表面的信息,一般在几至几十个埃左右,因此它是一种表面分析技...
X-rayphotoelectron spectroscopy(XPS) is the most broadly applicable surface analysis technique today. It relies on measurements of the energy distribution of photon-excited electrons from atoms in the surface region of the solid. It can detect all elements except hydrogen with a sensitivity that vari...
Chemical state X-ray photoelectron spectroscopic analysis of copper species is challenging because of the complexity of the 2p spectra resulting from shake-up structures for Cu(II) species and overlapping binding energies for Cu metal and Cu(I) species. This paper builds upon and extends previously...
