ABSTRACT

Amorphous silica nanoparticles were rapidly synthesized in a simple and cost effective way using a sol-gel technique from rice husk- a waste product of rice mill. Greener approach is used with low chemical energy utilization along with easily scaled up technique, thus minimizing the risk leading to harmful hazards. The silica nanoparticles were investigated for the surface topography and amorphous phase by SEM and XRD techniques. In the present research work, silica nanoparticles produced by green method were successfully revealed a good potential for the drug delivery application with inclusion of model drug onto mesoporous silica by calcination technique and also to act as a photocatalyst for methylene blue dye degradation.
