Hence, the XPS measurements excluded the presence of Cu2O and Cu(OH)2 impurities in the green-synthesized CuO NPs as there would be no satellite peaks observed in Cu 2p3/2 and Cu 2p1/2 of Cu+ [31,32]. The appearance of satellite peaks proved to be the presence of the fingerprint ...
For Cu 2p and O 1s, the HR-XPS scan was acquired from 930 to 970 eV and from 520 to 544 eV, respectively. The binding energy values can be used to derive information on the chemical and electronic structure state of Ti cations in TiO2 [32]. As shown in Figure 6a, the Ti 2p3/2...

3.5. XPS Analysis of CuO-CeO2/γ-Al2O3 Figure 6shows the Cu 2p XPS spectra of CuO/γ-Al2O3and CuO-CeO2/γ-Al2O3. CuO/γ-Al2O3shows signals of Cu2+at approximately 934.9 eV and Cu+and/or Cu0932.6 eV, respectively [28,29]. The XPS spectra of CuO-1% CuO/γ-Al2O3were ...
It’s found that the peaks of the as-prepared CuO/W18O49 composite samples with different CuO content only corresponded to W18O49, no peak associated with Cu, Cu2O, or CuO was observed, which may be due to the low content and high dispersion degree of CuO in the composite. However, ...
For the XPS spectrum of carbon-doped CuO/Fe3O4 composite catalyst (Figure 2a), the main peaks were C1s, O1s, Fe2p, and Cu2p, centered at around 285 eV, 530 eV, 720 eV, and 930 eV, respectively. The C1s XPS pattern of the sample is shown in Figure 2b. The spectrum contains two...
