Synthesis and characterisation of carbon nanotubes over modified mcm41 through cvd technique

Abstract

Carbon the sixth most abundant element in the universe has been newlineknown from ancient times Materials reduced to the nanoscale can suddenlyshow very different properties compared to what they exhibit on amacroscale enabling unique applications Carbon nanostructures haveattracted a great deal of interest due to the discovery of fullerenes Widely recognized as the quintessential nanomaterial carbon nanotubes CNTs havealready compiled an impressive list of superlatives since their discovery in1991 by the Japanese electron microscopist Sumio Iijima The basic structuralunit of carbon nanotubes is a graphitic sheet rolled into a cylinder with thetube tips closed by hemispherical or polyhedral graphitic domes newline newline
