Polyphasicity of both natural bentonite and catalysts based on the latter has been found by X-ray phase analysis and IR spectroscopy. In natural bentonite, the indentified phases were montmorillonite, α-quartz and calcite as an impurity. The formati

MnO2 samples were prepared via different procedures: (i) permanganate ion reducing with formic acid followed by the precipitate washing with cold (IS-Mn(1)) or hot (IS-Mn(2)) water, (ii) permanganate ion reducing with Mn2+ ion (IIS-Mn), and (iii) KNO

In the work, the kinetics of ozone decomposition over compositions containing bentonite anchored compounds of palladium(II) and copper(II) as well as bromide ions was studied. It has been found that bentonite by itself decomposes ozone; however, its

The catalytic activity of supported complexes of d metals in redox reactions with participation of gaseous toxicants, PH3, CO, O3, and SO2, depends on their composition. Owing to the variety of physicochemical and structural-adsorption properties of
