Mn2+on the EMR surface of the KMnO4 system mainly existed in the form of Mn3+, and the manganese oxides formed by the autocatalytic oxidaton of manganese mainly existed in the EMR system in the Fe-Mn oxidation state and residue state. This study provides theoretical support for developing ...

KMnO4 has unusual formal manganese valence state Mn+7 that seems puzzling: the energy of creating such ion (119 eV) is much greater than the energy of chemical bonds (up to similar to 10 eV). We have used the Wannier functions formalism to analyze the distribution of Mn-3d electrons and...

However, this technology as an advanced oxidation process for pretreating WAS is relatively unexplored. In the present study, we investigated an adjustable permanganate/sulfate (with KMnO4 and Na2SO3) method to enhance disintegrable performance with in situ-generated reactive Mn(III) species. The ...
In this work, MnO2/LaMnO3 catalysts derived from LaMnO3 perovskite were prepared in situ via a facile selective removal and oxidation method using acidic KMnO4 solution. For bulk LaMnO3 perovskite, the A-site cations (La) were dissolved and B-site cations (Mn3+) were simultaneously oxidized ...
In the case of heating in air, an opposite phenomenon—an exothermic peak accompanied by mass increase—was observed, corresponding to gradual oxidation of Zn to ZnO. Figure 2. DTA and TG curves for Zn in argon (upper) and air (lower). DTA/TG measurements conducted for the Zn/KMnO4 ...
