Catalysts are known to play an important role in chemical transformations and reactions as they increase the speed of a reaction, lower the activation energy for the reaction, act as a facilitator and bring the reactive species together more effectively, and create a higher yield of one species when two or more products are formed. Recently, nanocatalysts have begun being used because nanomaterials are more effective than conventional catalysts due to their extremely small size and very high surface area-to-volume ratio. Moreover, at the nanoscale, unique properties are found which are not present in their macroscopic counterparts. Hence, for synthesis of CNF, consideration of use of nanocatalyst is very important. In this chapter different types of catalysts and their various preparation methods were presented. Finally, synthesis of carbon nanofiber (CNF) using nanocatalysts were discussed with special emphasis.
