Abstract

Carbon nanotubes (CNTs) were synthesized by catalytic chemical vapor deposition of acetylene over metal ion-loaded LTA (linde Type A)template coated biomorphic carbon materials (BCMs). BCMs with 20- to 35-μm pore dimension were prepared by Cypress carbonization process in Ar atmosphere; thereafter, LTA crystals were synthesized and homogeneously coated on BCMs by an in situ hydrothermal process. We focused on the Co, Fe, Ni, and Cu nanoparticles, varying the catalyst nanoparticles for obtaining better CNTs yield and evaluated the crystallinity of CNTs. Multi-walled carbon nanotubes (MWCNTs) with an inner diameter of 9.54 nm, an outer diameter of 34.71 nm, and the yield of 15.50% were synthesized at 650 oC for 120 min with Co nanoparticles, and the ID/IG of 0.99 of CNTs was obtained
