Abstract
Metallic (Fe, Co, Ni, and Cu) ion-exchanged faujasite-type (FAU) zeolite was used to synthesize carbon nanotubes by catalytic chemical vapor deposition (CCVD). Based on the characterization with transmission electron microscopy (TEM), thermogravimetric analysis (TGA), and Raman spectroscopy, the carbon grown on different metal-supported zeolites (FAU) exhibited a variety of nanostructures such as tubes, belts, and fibers. High yields of carbon nanotubes (CNTs) of up to 63.1% and 60.2% were obtained from Fe- and Co-supported zeolite templates, respectively, and the latter had a greater crystallinity
