Optimization of the synthesis of carbon nanotubes to improve the efficiency of chemical posttreatments of the prepared material

Аннотация

We report the experimental results that allow optimizing the synthesis of multiwalled carbon nanotubes by chemical vapor deposition. The optimal composition of a catalyst and technique for its fabrication are found. The role of the hydrogen contained in the gas mixture is studied. The poured density of the synthesized material was decreased by 25% and the efficiency of the process almost doubled.
