A Facile Method for Preparation of Ag Nanoparticle Loaded MCM-41 and Study of Its Catalytic Activity for Reduction of 4-Nitrophenol
A simple chemical method has been reported for preparation of Ag nanoparticle (AgNP) loaded MCM-41 catalysts. This synthetic method involves in situ reduction of AgNO3 by citrate ions within the porous structure of MCM-41. The synthesized materials were characterized
by powder X-ray diffraction, high resolution transmission electron microscope and N2 adsorption–desorption surface area and pore size analyzer. The synthesized catalysts possess high surface area with regular pore structure and spherical AgNP inside the pore channels of MCM-41.
Synthesized AgNP incorporated MCM-41 materials showed the enhanced catalyst activity for the reduction of 4-nitrophenol to 4-aminophenol at room temperature.
