In this paper, organic compounds derived from biomass (ethanol, toluene, phenol,1-methylnaphthalene) were catalytically decomposed and reformed with steam over Fe/Al2O3 for obtaining of carbon nanotubes (CNTs), materials used in chemical sensors manufacturing for applications in medical devices or in optoelectronics. In the decomposition reaction, the oxygen functional group in ethanol and phenol initiated the hydrogen and CNTs production, while a low amount of toluene and 1methylnaphthalene were cracked, resulting hydrogen and amorphous carbon. In the reforming reaction, the hydrogen and CNTs yields sharply increased, more than 80% of ethanol and toluene was converted to CNTs. From 1-methylnaphthalene low amounts of CNTs were obtained..
