SYNTHESIS OF CARBON NANOTUBES VIA CATALYTIC DECOMPOSITION OF ACETYLENE ON BI-MET ALLIC SUPPORT INTERACTION OF CO-MO/MGO

Abstract

The research work investigate the viable utilization of acetylene as the precursor for the synthesis of carbon nanotubes (CNTs) with the aid of bimetallic Co-Mo/MgO support catalyst via catalytic chemical vapour deposition (CCVD). The experimental results show the presence of nano sized and hollow core of the tubular carbon structure. An increase in the heat treatment temperature enabled Co- Mo/MgO catalysts in growing CNTs at higher yield, the results show an increase in the diameter when the treatment temperature is raised from 700°C-800°C.
