Аннотация

Processes of deposition of multiwall carbon nanotubes in the synthesis by metal-organic chemical vapor deposition on hollow cylindrical substrates and the effect of the substrate area on the yield of the target product were studied. Making larger the tubular deposition reactor and the area of the cylindrical substrate enabled a substantial increase in the yield of carbon nanotubes. The technological synthesis parameters of the carbon material were optimized. Methods were developed for purification of carbon nanotubes by annealing in air, and materials were obtained with purity of no less than 98%. Physicochemical analysis methods were used to examine the structure and properties of the materials.
