| Abstract: | Highly ordered
cobalt substituted MCM-41 mesoporous molecular sieves was synthesized by direct
incorporation of cobalt into the MCM-41 framework through hydrothermal method.
The calcined Co-MCM-41 was characterised by physico-chemical technique. The
above-characterised material was tested for the application as catalytic template
synthesizing single walled carbon nanotubes (SWCNTs) using acetylene as a
carbon precursor by chemical vapour deposition (CVD) method in the temperature
range 700-900ºC. The well graphitised CNTs in the pores of Co-MCM-41 was
observed and confirmed by SEM and TEM. The good thermal stability and high
productivity observed in this study suggest that the mesoporous molecular
sieves could be a promising catalytic template for synthesizing carbon
nanotubes. |
