We have measured Mn-2p photoemission spectra in Mn perovskites doped by two methods: La 1 xCa xMnO 3 and LaMnO 3+ δ. Intra- and inter-series comparisons reveal that the position and intensity of the Mn-2p satellite depend only on the level of doping, and that it can always be decompo...
Although nu-merous studies exist of the products of Mn oxidation(Foord et al. 1984; Di Castro and Polzonetti 1989) weare unaware of any that compare and contrast X-ray pho-toelectron spectra (XPS) 2p multiplet structures of Mn21,Mn31, and Mn41in oxides and oxyhydroxides or comparethem...
随着Mn含量从2%增加到4%,金属Zn的含量从21.5%下降到14.5%,这可能是由于过量Mn的加入抑制了ZnO还原为金属Zn。 ▲Fig.5.In situ XPS of (a) Cu 2p, (b) Cu LMM, (c)Zn 2p and (d) Zn LMM on the CZA-xMn surface...
In this study, the XPS spectra information was used comprehensively, including the comparion of the peak-to-peak shape of the Mn 2p spectra, the Mn 3s spectra peak splitting spacing, the change of adsorbed oxygen and the content of elements on the catalyst...
