Effect of reaction parameters on the growth of MWCNTs using mesoporous Sb/MCM-41 by chemical vapour deposition

► Synthesis and characterization of ordered mesoporous MCM-41 materials. ► The better formation of MWCNTs were obtained over 2 wt.% of Sb/MCM-41 at 800 °C. ► Sb loaded MCM-41 is one of the good catalytic support for the growth MWCNTs. ► Sb/MCM-41 produced MWCNTs having several internal compartments. ► These MWCNTs may induce the storage capacity in respective fields.
