Interpretation of XPS spectra Interpretation of O1s spectra is not straightforward. Apart from metal oxides, the O1s binding energy of many compounds and species falls within a very narrow range. O1s peaks tend to be broad, with multiple overlapping components. Components due to wa...
具体操作:分别点另一个窗口中的Rigion Peaks下方的0、1、2等可看每个峰的参数,此时XPS峰中变红的为被选中的峰。在弹出来的参数窗口中调整峰位置,半峰宽,峰面积等参数,然后点击accept。反复调节,尽可能让拟合出来的数据和原始数据重合。 第六步:拟合数据保存与导出 拟合完毕之后,点击XPS peak processing 中的Save...
Several parameters, such as the FWHM of the V2p_(3/2) and O1s XPS peaks, their shape and binding energy difference, have been utilized. The characterization is extended to these oxides following different sample treatments. The effect of the presence or absence of adventitious carbon on the ...
同时在XPS测试里,MWNO电极循环前后的金属阳离子的价态始终如一,这再次证明了MWNO材料的电化学稳定性。 Figure 7.Studies of cycling effect on the MWNO electrode. a) XRD patterns of the pristine and cycled MWNO electrodes. ...
A detailed XPS study of several oxides of vanadium is reported in this work, in an attempt to characterize clearly the surface of these oxides. Several parameters, such as the FWHM of the v2p32 and O1s XPS peaks, their shape and binding energy difference, have been utilized. The characteriz...

aThe presence of surface oxygen vacancies was evaluated by studying the O1s XPS spectra, as shown in Fig. S3. The spectra were deconvoluted into three component peaks, assigned to lattice oxygen (OI, _529 eV), surface oxygen, OH groups and oxygen vacancies (OII,531 eV), and adsorbed water...
To understand the source responsible for the excellent OER activity of P-Bi0.1BSCF, the surface state of BSCF, Bi0.1BSCF and P-Bi0.1BSCF catalysts is intensively studied by XPS analysis. The O1s XPS spectra for BSCF, Bi0.1BSCF and P-Bi0.1BSCF is deconvoluted to four characteristic peaks (...
The O 1s XPS binding energy of post-OER Ir-Co3O4 shifts to a more positive position, further confirming the increase of valence state on overall catalyst after the stability test (Supplementary Fig. 25). The stabilities of Ir- Co3O4 and IrO2 were further tested at a higher current ...
