Structural and adsorptive properties of modified carbon nanotubes
Анотація
Carbon nanotubes obtained by acetylene pyrolysis on iron containing catalysts. Nanotubes as synthesised modified ultrasonic processing in a solution of the concentrated nitric acid. Samples obtained with different concentration of oxigen on surface by calcination in inert atmosphere of argon at 770, 1070 and 1470 °K. Structural and adsorption properties modified carbon nanotubes were studied. It is revealed, that with rise in temperature of calcination samples concentration of oxygen decreases for surfaces and their specific surface from 637 to 176 m2/g.
