The effect of water vapor on carbon nanotubes, synthesized by the method of thermal catalytic deposition from the gas phase on a substrate, covered preliminary by the iron layer of 0.8 nm, was studied. Methane was used as a feedstock gas, hydrogen and argon as a buffer gases. The multilayer carbon nanotubes were synthesized. According to analysis of carbon nanotubes by the methods of Raman spectroscopy and transmission electron microscopy, increasing the concentration of water vapor up to 0,2 ‰ leads to complete etching of the amorphous carbon surface of the carbon nanotubes.At high concentrations of water vapor 0.2 - 1 ‰ structure of multi-walled carbon nanotubes changed to bamboo.The highest quality of graphite structures is achieved at water vapor concentration of 0.35 ‰..
