Abstract: The present study focuses on a novel route processing for the synthesis of carbon nanotubes on a zeolite-coated biomorphic carbon template (ZCBCT). First, a biomorphic template with a pore dimension of 20-35 μm was prepared by carbonising Pinus resinosa wood under an Ar atmosphere. Single-phase zeolite crystals with a crystal size of 0.3 μm were then synthesised and homogeneously coated on a BCT using an in situ hydrothermal process. Finally, MWCNTs that were synthesised on Co-metal nanoparticles were loaded onto the ZCBCT with C2H2 as a carbon source using the catalytic chemical vapour deposition (Cat-CVD) method. In this study, we focused on varying the reaction time and temperature for obtaining a better CNT yield, and the CNT characterisation morphology, crystallinity, and surface area were evaluated. The MWCNTs with an inner diameter of 5.3-9.8 nm were synthesised at 650°C, and the duration of the CNT ID/IG of 1.00 is from 60 min to 180 min.

Keywords: multiwalled carbon nanotubes; biomorphic materials; Pinus resinosa; zeolite; catalytic chemical vapour deposition.
