FIELD: chemistry. ^ SUBSTANCE: invention can be used in power engineering, electronics, chemical engineering, defense industry and medicine. The nitrogen-containing carbon material with nanotube structure is prepared through decomposition of a vapour-gas mixture containing the following in mol %: 2-6 N,C-containing compound, 0-98 Ar and 0-50 H2. Decomposition is carried out at temperature of 700-800C and pressure of 1 atm in the presence of a Au/Al2O3 catalyst with average Au particle size not greater than 20.0 nm and an iron compound. The iron compound used can be ferrocene (5-C5H5)2Fe; Fe(III) ferrocyanide, Fe4[Fe(CN)6]3; Fe(III) acetylacetonate, (C2H7O2)3Fe; Fe (II) acetate, Fe(CO2CH3)2; Fe(III) nitrate, Fe(NO3)3ù9H2O; Fe pentacarbonyl, [Fe(CO)5]. The N,C-containing compound used can be pyridine, pyrazole, acetonitrile, dimethylformamide. The catalyst contains the following, in wt %: 0,1-5.0 Au, 0.1-0.5 Fe, the rest - Al2O3. ^ EFFECT: high output of carbon and high content of nitrogen in the obtained nanotubes. ^ 5 cl, 6 ex, 2 tbl, 3 dwg |
