Effect of cation insertion on the stability of gliding arc plasma-precipitated mesoporous MnO2 dye bleaching catalysts

α-MnO 2 and γ-MnO 2 polymorphs were, respectively, obtained from the plasma precipitation of KMnO 4 and Mn(CH 3 COO) 3 ⋅2H 2 O precursors. The obtained powders were calcined at 150 °C, 210 °C and 400 °C, and characterized by X-ray diffraction, Raman spectroscopy, Fourier transform infrared spectrosc...
