Abstract

2.3 x 10^-3 wt% multi-walled carbon nanotube incorporated silica aerogel (MWCNT/Silica aerogel) was synthesized by
ambient pressure drying. The as-synthesized MWCNT reinforced silica aerogel was characterized by XRD, SEM, N2-adsorption–
desorption, etc. The MWCNT/Silica aerogel catalyzed a multicomponent reaction for synthesizing medicinally important
benzylpyrazolyl coumarin derivative. And, in another application, the efficient decolorization of Eriochrome Black T and
Methylene Blue from their respective aqueous solutions over MWCNT/Silica aerogel was also investigated using UV
spectrophotometer. A comparison has also been made with decolorizing activities of silica gel and activated charcoal.
