The presence of CuO and Cu2O was confirmed using high-resolution O1s spectra. The characteristic peaks observed at 530.2 eV belong to Cu-O, -C=O bonding in GO/CuO. The peak shown at 532.9 eV was assigned to oxygen present in GO. The XPS spectrum of Cu 2p showed a peak at 932.5 eV...
.502,用XRD、SEM和XPS对催化剂结构进行了表征分析,考察了不同CuO掺入量对葡 甲苷的伯羟基选择氧化合成葡萄糖醛酸及其内酯的催化活性的影响。结果表明,CuO的掺入对载体的孔结 构及活性组分在载体表面的分散都得到了不同程度的改善:ce.Cu.Mn的协同作用有利于提高Pd的氧化还 ...

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...
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...
Figure 6. Core XPS analysis for CuO/ZnO nanocomposites with different ratios synthesized by P. corylophilum As-1. O 1s is deconvoluted into four peaks of the all series of the precipitates, which confirms the presence of metal as oxides (i. e. CuO and ZnO), sharing with Na–O (in Zn...
