However, although it is known that the chemical state identification in manganese by XPS is difficult due to the presence of a complex multiplet splitting [A-D], this has not been taken into consideration in the deconvolution of the XPS spectra for Mn 2p3/2. This disregard has affected the...
Fig. 7. Mn 3s XPS spectra of different structured MnO2 (Huang et al., 2019b). In addition, Mn3p, Mn3s, and Mn2p3/2 XPS spectra can be used to obtain the abundance of Mn(II), Mn(III), and Mn(IV) on the manganese oxide surface, which can then be used to help understand the...
Calculated Mn(2p 3/2 ) X-ray photoelectron spectra (XPS) of Mn 2+ , Mn 3+ , and Mn 4+ free ions are strikingly similar to Mn(2p 3/2 ) spectra of Mn 2+ -, Mn 3+ -, and Mn 4+ -oxides and oxyhydroxides, indicating that these ions adopt high spin states in M
Presents a study which focused on the 2p3/2 X-ray photoelectron spectra (XPS) of Mn2+, Mn3+, and Mn4+ ions of some Mn-bearing oxides and oxyhydroxides, including manganite and synthetic birnessite. Information on experimental procedures used; What controls the formation rate of birnessite; ...
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...

XPS data show that Mn2 þ and Mn4 þ valences in both 2p and 3s chemical states. The XPS spectra are fitted to Mn 3 s doublets, which are split by 5.7 eV (Mn2 þ ) and 4.5 eV (Mn4 þ ), respectively. The integrated intensity ratio of Mn2 þ and Mn4 þ is ...
The shift in the binding energy of the Mn 3s peaks indicated a change in the oxidation state of Mn. The presence of a 5.9 eV interval in the spectrum corresponds to the Mn2+ state, suggesting the existence of MnO bonds.33,34 All peak positions in the XPS spectra are listed in Table ...
