Carbon for selective oxidative dehydrogenation reactions
Zusammenfassung:
Low-cost mass production of CNTs becomes prerequisite for their applications in chemistry and catalysis in which the availability of large amounts of material with well-defined surface, chemical and mechanical properties is required. Natural occurring iron oxides in volcanic lavas are used as catalysts for CNT synthesis in the well-established CVD (chemical vapor deposition) process while the lava itself acts as support. As in a common CVD process, the quality of the CNTs can be controlled by the synthesis parameters such as flow rate, hydrocarbon to hydrogen ratio and growth temperature.
