Carbon nanotubes synthesized in zeolites UTD-1, UTD-18 and UTD-12

Abstract

Single walled carbon nanotubes (SWCNT) were prepared in the channels of the 14MR zeolite UTD-1, 12MR zeolite UTD-18 and the 10MR zeolite UTD-12 via vacuum pyrolysis. The organometallic templates for these zeolites serve as both carbon source and catalyst for the intrazeolite growth of the nanotubes. Characterization by TEM, SEM and Raman spectroscopy indicate the diameters of the SWCNTs are on the order of 0.6, 0.5 and 0.4 nm respectively
