Dukhno I. Synthesis and electron-donating properties of N-, O-containing active carbons

The subject of study is sorption catalytic, ion exchange and electrochemical processes with N-, O-containing active carbons. The goal is definition of active carbons electron-donating properties in dependence on contains and chemical state of nitrogen and oxygen atoms. Methods: ir- and x-ray photoelectron spectroscopy, photocolorimetry, thermogravimetry, chromatography, red/ox titration, pH-potentiometric, qualitative chemical analysis of elements, kinetics of oxidation-reduction processes. The way of regulation of contains and chemical state of nitrogen and oxygen atoms in active carbons has been proposed. The methods of synthesis of active carbons modified with nitrogen and oxygen heteroatoms have been developed. The electron-donating ability of synthesised N-, O-containing carbons on the basis of its reduction ability, catalytic activity and surface potential measurements has been investigated. Including of pyrrole and pyridine nitrogen heteroatoms, carbonyl and ether oxygen atoms to active carbonsstructure lead to increase (presenting of heteroatoms both types lead to the greatest) of electron-donating ability have been shown. The correlation between experimental dates and quantum chemistry calculations of carbons clusters power parameters has been established.
