Carbon in Catalysis
Abstract:
The Mount Etna lava stones containing iron oxide particles can be used as catalyst and support to synthesize and immobilize carbon nanotubes and nanofibers. We report on the use of the obtained composite as catalyst for butadiene and styrene production. The catalyst is highly active in the mentioned oxidative dehydrogenation reactions and stable. The whole process is energy-saving, environmentally friendly, technically feasible, and with great potential for industrialization: from the syntheses of carbon nanotubes and nanofibers until their use in the catalytic reactions, no any wet-chemical pretreatment of lave stone or activation of catalyst is needed.
