Effect of Calcination and Reduction Process on MWCNT Growth during Synthesizing MWCNT-Alumina Hybrid as Composite Reinforcement

Multiwall carbon nanotube (MWCNT) and alumina hybrid compound prepared via chemical vapour deposition (CVD). The CVD process always reported that the catalyst must undergo calcinations and reduction process before growing the carbon nanotube (CNT). In this work, MWCNT-alumina hybrid was successfully synthesized via simple CVD method. The morphologies study showed that the MWCNT-alumina hybrid with calcination and reduction, and calcination without reduction has been successfully synthesized.
