| Summary: | Using the method of X-ray photoelectron spectroscopy (XPS),
a comparative analysis of the structure and chemical state of
multi-walled carbon nanotubes doped with nitrogen during their
synthesis, as well as by high-dose irradiation with nitrogen ions,
is carried out. It is shown that the chemical state of nitrogen
in the walls of MWCNTs doped with various methods differs
significantly. It was found that the use of ion irradiation allows one to obtain MWСNTs with a higher nitrogen concentration in
the structure of the outer walls. However, there is a significant
increase in the degree of imperfection of the crystal structure
of the walls of carbon nanotubes and the formation of oxygencontaining functional groups. The features of the chemical state of
nitrogen in the walls of MWCNTs using various alloying methods
are established. The results obtained in this work can be used to
develop methods for modifying the electronic structure of carbon
nanostructured materials. |
