Variations of Furnace Affecting the Catalytic Chemical Vapour Synthesis of Carbaon Nanotubes - A Review

Ritu Malik

Abstract: Carbon nanotubes are the finest example of the crystallized form of carbon. They are basically the rolls of graphite sheet which are electrically and thermally more conductive, mechanically more stronger and biologically and chemically more active. The purpose of CNTs production could be different. It could be application based or research based and sometimes could be commercial based. These purposes could be best served with catalytic chemical vapor deposition technique assembled with suitable reactor. Recent advancement in direction of CNTs production have shown the experimentation with the apparatus which are designed to follow the most popular technique of CCVD. Variation in designs of reactors serves different needs which could be controlling the product morphology, optimizing the productivity or scaling up the process. This letter discusses a general overview on the suitability of apparatus for conducting CCVD and the focus will be on the most popular and basic designs of the reactors for the production of CNTs.
