摘要：
The hydrothermal treatment of neutral and acidified KMnO4 solutions at concentration of 0.037-0.093 mol/L and temperature of 120, 170, and 220 degrees C for 24 h leads to selective synthesis of three different manganese dioxide modifications: alpha-MnO2, delta-MnO2, and beta-MnO2. The temperature of hydrothermal treatment and medium acidity has been shown to affect considerably the phase composition of KMnO4 reduction products and reaction yield. The obtained samples of MnO2 have been characterized by X-ray diffraction, scanning electron microscopy, Raman spectroscopy, and diffuse reflectance spectroscopy.
