Abstract
crystal films of manganese oxide of composite materials were investigated by the method of X-ray photoelectronic spectroscopy in the fresh and spent state. The efficiency of modification was confirmed whereby on the surface of substrates of the carbonate type forms a thin-film crystalline structure of MnO2. We have found the relationship between the structure of crystalline film and substrate nature, which affects technical characteristics of the sorbent–catalyst. The mechanism of catalytic oxidation of manganese compounds in aqueous solutions using synthesized sorbents–catalysts was defined.
