Abstract

The novel processing route for the synthesis of carbon nanotubes (CNTs) on silicalite-1 template coated biomorphic carbon is reported in this paper. First of all, biomorphic carbon with 20-35μm pore dimension was prepared by carbonizing Cypress under Ar atmosphere, thereafter, a silicalite-1 crystals were synthesized and homogeneously coated on biomorphic carbon by an in situ hydrothermal process. Finally, multi-walled carbon nanotubes synthesized on the Co-metal nanoparticles loaded silicalite-1 template loaded on biomorphic carbon with acetylene (C2H2) as a carbon source by the catalytic chemical vapor deposition (CCVD) method. In this study, we focused on varying the reaction time for obtaining better CNTs yield and the characterization morphology, crystallinity, surface area of CNTs were investigated. Multi-walled CNTs with inner diameter of 7.31nm and outer diameter 38.53 nm and the maximum yield of 23.71% nm were synthesized at 650°C for180 min and the ID/IG of 0.97-1.00 of CNTs was obtained.
