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.
