Large-scale insitu synthesis of Fe-filled carbon nanotubes was achieved by chemical vapor deposition (CVD) with anhydrous FeCl3 as floating catalyst precursor and ethylene as carbon source. The effects of catalyst and carrier gas were studied. The as-grown products were characterized using SEM, TEM, XRD, Raman, and vibrating sample magnetometer techniques. It has been found that for the floating CVD technique, anhydrous FeCl3 is a good yet cheap catalyst precursor that is better than the traditional ferrocene catalyst in terms of the purity and filling ratio of the Fe-filled carbon nanotubes produced. The superparamagnetic property of the carbon nanotubes was also demonstrated by vibrating sample magnetometry.
