Carbon nanotubes (CNTs) are broadly synthesized at high temperature ranges using floating catalyst chemical substance vapor deposition (FC-CVD) technique. It is important to lessen the synthesis temp of CNTs to avoid the self-pyrolysis of hydrocarbon to improve the development of CNTs. This function was tackled to synthesize CNTs at low temperatures using some improvements on the technique utilized. In-situ monitoring gadget was utilized to monitor the heat profile in the reactor and therefore, to initiate the response. The preheating temperatures was investigated in the ranging of temperatures between 300°C and 150°C at 50°C interval. Ferrocene and benzene were used as the Carbon source and catalyst precursor, respectively. Estimating the minimal pyrolysis temp of benzene was completed in the lack of catalyst. Predicated on the outcomes of characterization methods, multi-walled CNTs with high purity have already been synthesized at synthesis heat range of 600°C. This work offers fairly low synthesis heat range of CNTs gives real chance to synthesize CNTs for microelectronic applications. Keywords: Carbon nanotubes, Floating catalyst, Preheating heat range, In-situ monitoring, Thermo gravimetric evaluation Introduction: In the last 10 years, carbon nanotubes (CNTs) have obtained an enormous interest from scientists because of nanoscale sizes and promising physical properties (1), (2). Various strategies have been utilized to synthesize CNTs, such arc discharge, laser beam ablation, and chemical substance vapor deposition (3), (4), (5). Chemical substance vapor deposition (CVD) is definitely the best in comparison to other methods because of low cost and also it includes lowest synthesis temperature (6), (7). This technique could be conducted via assisting catalyst or floati...
