Furthermore,phenomena,such as the vibration absorption peak at 617 cm'1 identified as the Cu-S bond in the FT-IR spectra,and the unchanged peak intensity and position in the XRD spectra further confirm that sulphidization occurs at the surface of copper oxide.孙和云...
The XRD pattern revealed the orientation and crystalline nature of material. Fig. 1 shows the X-ray diffraction pattern of the prepared sample. The XRD peak position was consistent with the copper oxide and the sharp peaks with high intensity indicated the crystalline nature. The peaks observed ...
The micro strain is the root mean square of the differences in the lattice parameters across the sample, which results in a broadening of the XRD lines without changing the peak position. The fraction of layers which exhibit stacking sequence faults in each crystal is known as the stacking ...
The XRD peaks of the CuO film show a large full width at half maximum (FWHM) of the peaks and low intensity, which most probably is due to the small grain size of CuO nanoparticles, that construct the CuO film. The absence of any other copper species peaks in the XRD patterns proves ...

(step time: 1s; 2θ range: 5.0–90). The sizes of particles within as-synthesized samples were estimated using Debye-Scherrer’s equation, which was applied to the most intense peak observed in the XRD patterns. The surface functional groups of the as synthesized samples were identified after...

(Fig.1a2). XRD results confirmed the formation of CuO NPs (Fig.1c). Flower-like CeO2NPs were grown on the CuO NPs catalyst by electrodeposition (Fig.1b). The flower-like CeO2NPs morphology with thin petals was expected to be near ideal for promoting PEC CO2reduction on the hybrid ...
S5 for peak assignment). The presence of the three different phases confirms the formation of the thin (several microns) double layer consisting of an intermediate Cu2O and outer CuO nanowire array layers. The XRD pattern of CuO(NWA)|Cu2O(NPy) shows essentially the same signals, although the ...
