Synthesis, characterization and catalytic activity of cryptomelane/montmorillonite composites
Original language description
Manganese oxides are considered to be highly effective catalysts for the oxidation of volatile organic compounds (VOCs). A series of MnO2 /montmorillonite composites was prepared to test their catalytic activity in the combustion of model compounds - toluene and ethanol. Several different types of montmorillonites (Mt), referred to as STx-1b, SWy-2, SAz-2, and Kunipia- F, were used to prepare the composites. The MnO2/Mt composites were synthetized in a weight ratio of 1:1, using the reaction between KMnO4 and HCl for the generation of the MnO2 component. Advanced techniques including XRD, SEM/EDS, IR spectroscopy, N2 adsorption /desorption, and H2 TPR were used for physico-chemical characterization of obtained materials. The MnO2 component precipitated as cryptomelane, the tunnel α-MnO2 structure. In catalytic tests, all composite samples were more active than the reference MnO2.
