Abstract

The production of carbon nanotubes (CNTs) was successfully synthesized using the tubular microwave chemical vapor deposition technique, using ferrocene as a catalyst and acetylene (C2H2) and hydrogen (H2) as precursor gases. Production of CNTs depends on various process parameters such as microwave power, radiation time, and the gas ratio of C2H2/H2 was investigated using a central composite design. The statistical analysis revealed that the optimized conditions for the most weight of CNTs production were at 900W microwave power, 35minutes radiation time, and 0.6 gas ratio of C2H2/H2. The quality of CNTs was examined using Raman spectra, Brunauer, Emmett, and Teller surface area, and Zeta potential. The morphology and the structure of CNTs produced were characterized using a field emission scanning electron microscope and high-resolution transmission electron microscope. These analyses revealed that multiwall CNTs consistently scattered vertical alignment have diameters ranging from 10 to 29nm. © 2024 Elsevier Inc. All rights reserved.
