Synthesis of Ag nanoparticles within the pores of SBA-15: An efficient catalyst for reduction of 4-nitrophenol

Abstract

Synthesis of uniform, spherical and rod shaped Ag nano particles within the uniform pore channels of mesoporous silica SBA-15 have been reported via a simple chemical method. High resolution transmission electron micrographs showed uniformly distributed spherical and rod shaped nano particles inside the pore channels of SBA-15. Synthesized Ag nano particle incorporated SBA-15 materials were acted as an efficient catalyst for the reduction of 4-nitrophenol to 4-aminophenol.
