Raman spectroscopy has proven to be a powerful, local structural probe for MnO2.δ-phase MnO2 has strong Raman-active (Mn-O) stretching transitions at 646 and 575 cm-1. A somewhat weaker transition at 510 cm-1 is also prominent but less intense in most δ-phase MnO2 samples. All three ...
Deposition of the MnO2layer (by the reduction of KMnO4with by K2C2O4in an alkaline condition) on hollow silver nanoparticles (h-Ag) has been also analyzed. Hollow silver shells are significantly less stable than the solid Ag nanostructures and are practically entirely destroyed during the ...
