Synthesis of Carbon Nanotubes on Zeolite Substrate of Type ZSM-5
The present work deals with the synthesis of carbon nanotube-zeolite composites using as method the catalytic liquid spray pyrolysis. The nanotubes were formed after pyrolysis of toluene on the surface of a zeolite of type ZSM-5, which was used as a catalytic substrate. ZSM-5 zeolite was synthesized using the autoclave process and full characterized. Prior to the pyrolyses, the catalytic substrates were produced by mixing a certain amount of zeolite with a solution of Fe(NO3)3•9H2O of specific concentration. The obtained materials from the spray pyrolysis were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetry-differential analysis (TG-DTA).
