General description
Silica gel is a rigid 3D network of colloidal silica. It is exclusively used as a support material for the active titanium (III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation leading to form uniform polymer particles with narrow particle size distribution and high bulk density. Silica gel is classified as below:
a. Aquagel - pores are filled with water
b. Xerogel - by the process of evaporation, aqueous phase in the pores are removed
c. Aerogel - solvent removed by supercritical extraction.

In this report, procedures are discussed for the enrichment of single-walled carbon nanotube (SWNT) types by simple filtration of the functionalized SWNTs through silica gel. This separation uses nanotube sidewall functionalization employing two different strategies. In the first approach, a
