Description
Summary:The formation of carbon nanohorn (CNH)amulti walled carbon nanotube (MWCNT) hybrids was accomplished using chemical vapour deposition at 950 degree C. A bio-renewable resource, palm olein, and a mixture of zinc nitrate and ferrocene were used as the carbon precursor and catalyst, respectively. The hybrid shows good graphitic quality and a high aspect ratio of the aligned MWCNT. The estimated lengths and diameters of CNH are about 100a400 and 50a100 nm, respectively. It is believed that the surface of the ZnO particles was impregnated by the metal irons from ferrocene and grouped them together, which then served as a base for the formation of bundles of aligned MCWNTs.
