Enhanced clustering tendency of Cu-impurities with a number of oxygen vacancies in heavy carbon-loaded TiO2 - the bulk and surface morphologies

Abstract

The over threshold carbon-loadings (~ 50 at.%) of initial TiO 2 -hosts and posterior Cu-sensitization (~ 7 at.%) was made using pulsed ion-implantation technique in sequential mode with 1 hour vacuumidle cycle between sequential stages of embedding. The final Cx-TiO 2 :Cu samples were qualified using XPS wide-scan elemental analysis, core-levels and valence band mappings. The results obtained were discussed on the theoretic background employing DFT-calculations. The combined XPS-and-DFT analysis allows to establish and prove the final formula of the synthesized samples as Cx-

Bulk In2O3 crystals grown by chemical vapour transport: a combination of XPS and DFT studies

“…Ref. [25]) thus the transformations of the band intensity and shape as a function of the defects type and concentration are exclusively related to oxygen defects [26]. The difference between the literature [24] and the CVT data is plotted in Fig.…”

Mg–C Interaction Induced Hydrogen Uptake and Enhanced Hydrogen Release Kinetics in MgH2-rGO Nanocomposites

“…The XPS of hydrogenated pure rGO is presented in Scheme S7. Figure shows the deconvoluted π band in C, Mg-3s, O-2p (∼7–8.3 eV , ), and Fermi level ( E f ), which constitute the valence band spectra (Scheme S8) of the samples. The π and σ band spectra of all of the samples are presented in Scheme S9.…”

Synthesis of copper nano/microparticles via thermal decomposition and their conversion to copper oxide film

“…This finding is compatible with XPS data of the literature (See Table 2 ) [ 28 , 29 ]. Strong shake-up satellite peaks have not seen in two binding energy ranges of 938–946 eV and 958–966 eV for this sample [ 30 – 34 ]. This indicates that there is no CuO in the sample.…”
