The peak positions and peak shape parameters of Fe 3p for Fe2+ and Fe3+ were derived from the Fe 3p XPS spectra of the standard samples of 2FeOSiO and Fe O , respectively. 2 2 3 Using these parameters, the Fe 3p peaks of Fe3O4 and Fe1yO are analysed. The results indicate that ...

By curve fitting the spectra of these standard samples, the principle parameters in Tougaard's formula were obtained. Using these parameters, the experimentally determined XPS spectra were analysed and the relative concentrations of Fe2+ and Fe3+ were estimated. However, the composition of their Fe1...
Analysis of XPS Spectra of Fe2+ and Fe3+ Ions in Oxide Materials [J] In spite of the enhanced catalytic performances exhibited by the doped transition nano-metal catalysts, understanding and unraveling the mechanistic part b... Y Turu,H Peter - 《Applied Surface Science》 被引量: 0发表: ...
An attempt was made to correlate such a composition dependence of the catalytic activity to the nature of the surface of the alloy catalysts by using X-ray photoelectron spectroscopy. XPS analysis revealed that the surface layer was rich in platinum and deficient in nickel, but the surface ...

This review is to be considered part of the development of the MEMORI dosimeter, to evaluate the impact of climate (relative humidity, temperature, illumination, etc., including volatile organic compounds) on moveable objects. In the framework of the MEM
Majumdar…X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Atomic Force Microscopy (AFM) have been used to characterize GO before and after irradiation. Results indicate that GO exposed to high-energy radiation is converted to an amorp… COMPARING EXISTING MAC TABLES – ...
