A PROCESS FOR THE SYNTHESIS OF NANOTUBES OF TRANSITION METAL DICHALCOGENIDES

摘要

The invention relates to a process for the synthesis of nanotubes of transition metal dichalcogenides by the method of chemical transport with the addition of fullereness. According to this process nanotubes of transitioln metal dichalcogenides are obtained. Teh nanotubes are hexagonally arranged in form of needle-like bundles. The process comprises the method of chemical transport, in which besides halogens (iodine and/or bromine) also fullereness are used at conditions, in which the fullereness exist in the vapour phase. The chemical transport reaction occurs in a quartz ampoule, sealed at an pressure lower than 5 x 10<-3> Torr. The temperature in the hot part of the ampoule is higher than 830 DEG C.
