PROCESS OF SYNTHESIS OF NANOTUBES OF TRANSITION METALS DICHALCOGENIDES

摘要

The invention refers to the process of synthesis of nanotubes of dichalkogenides of transition metals according to the method of chemical transport with addition of fullerenes. Nanotubes of dichalcogenides of transition metals are obtained by this process. The nanotubes are arranged hexagonally in the form of needle-like bundles. The process comprises the method of chemical transport where besides halogens (iodine and/or bromine) fullerenes are also applied under conditions where the latter are to be found in the vapour phase. The chemical transport reaction is taking place in a quartz ampule which is flame-sealed at the negative pressure greater than 5x10-3 torr. The temperature in the hot part of the ampule is higher than 830 degrees Celsius.
