Existing state and solidification characteristics of heavy metals in glass‐ceramics from Mn‐bearing blast furnace slag

“…In order to detect the electronic properties of the element in glass‐ceramics, XPS is used for the qualitative analysis of valence states of Mn and Figure 4 shows the XPS fitting spectra of Mn2p in sample Mn7 since manganese ions in glass‐ceramics are mainly present as Mn 2+ and Mn 4+ . The final valence state of manganese can be obtained by determining the oxidation state according to the peak position, full width at half maximum (FWHM)/eV and multiplet splitting 32–34 . Table 2 shows the valence state distribution of Mn in sample Mn7.…”

“…The final valence state of manganese can be obtained by determining the oxidation state according to the peak position, full width at half maximum (FWHM)/eV and multiplet splitting. [32][33][34] Table 2 shows the valence state distribution of Mn in sample Mn7. It can be observed by XPS fitting that the oxidation states of manganese in sample Mn7 are MnO and MnO 2 , which corresponds to Mn 2+ and Mn 4+ in glass-ceramic, respectively.…”

Novel Two-Dimensional MoC/MnSe Composites for Supercapacitors and Hydrogen Evolution Reaction

“…These include lower catalytic activities and poor stability when compared to noble metals like platinum and gold, which are known for their excellent catalytic properties. 26,27 To attain optimal electrocatalytic performances, enormous efforts have been devoted to exploring a series of modification strategies to adjust their catalytic atoms and bond microenvironments, including phase modulation, construction of heterojunction, defect engineering, element doping, etc. 28−30 On the other hand, molybdenum carbide (MoC) has garnered significant attention due to its unique physicochemical properties with large surface area and proper surface atomic configuration, which is potentially explored in electrochemical energy applications.…”
