ABSTRACT
The conditions of copper (nickel)/carbon nanocomposites modification by such substances as silica (or silica gel), ammonium polyphosphate (or polyphosphoric acid), and ammonium thiosulfite (or sulfur) are substantiated in this chapter. The mechanochemical modification mechanism of correspondent nanocomposites is proposed. The results of modified nanocomposites production with the mechanism confirmation are discussed. The structures and properties of modified nanocomposites are investigated 230by the following methods: X-ray photoelectron spectroscopy, radiography, IR spectroscopy, transition electron microscopy. The structural changes of modified nanocomposites as well as increase in the metal atomic magnetic moments are presented. In the phosphorus containing Cu/C nanocomposites, the copper atomic magnetic moment is increased from 1.3 to 3 µB, and the oxidation state of phosphorus atom is decreased from 5 to 0, according to X-ray photoelectron spectroscopy.
