2023年6月15日 · Block-Approach allows for accurate fitting of metal and oxide signals in Cu 2p. Peak-fitting parameters for improved fitting of Cu 2+ in quantitative XPS. The photoemission spectra of Cu 2 p are one of the most studied.

2021年2月9日 · X-ray diffraction studies revealed that these copper-based oxide nanoparticles display different crystal structures such as cubic (Cu 2 O), monoclinic (CuO) and orthorhombic [CuNa 2 (OH) 4]. The...

The surface electronic states and elemental composition of CuO nanocoating on SS substrate were analyzed via X-ray photometry spectroscopy (XPS) and the results displayed in Figure 7 are...

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.

Using XPS and x-ray-excited Auger electron spectroscopy (XAES), we have studied the variation in surface composition of CuO and Cu2O with a variety of high-vacuum treatments, including vacuum annealing, oxidation and hydrogen reduction.

2014年2月1日 · We have calculated the effective energy-differential inelastic electron scattering cross section for XPS, including both surface and core hole effects, within the dielectric response theory by means of the QUEELS-XPS software (QUantitative analysis of Electron Energy Losses at Surfaces for XPS).

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

We report the catalytic activity and mechanism of copper (I) phosphide, Cu3P, with predominant [00Ι] facet exposure for the electrochemical reduction of CO2 (CO2RR) to formic acid.

2015年11月1日 · The experimental XPS spectra of pure Cu and CuO were excited with a non-monochromatic Mg Kα X-ray source, while the Auger spectrum of pure Cu was obtained with an Al Kα source.

CuO nanoparticles were characterized by using XRD, XPS, PL, SEM and TEM technique. In XRD analysis, significant peaks appeared at 18.3, 24.4, 33.6, 34.6, 35.2, 38.2 and 42.7 respectively. The...
