ABSTRACT:

Silica was prepared from bagasse ash using cation exchange resin method which resulted in high purity silica xerogels. The silica xerogel was then nanostructured using templating concept, templates with and without swelling agent was investigated. The porous silica was obtain with macro pores. The presence of swelling agent resulted in ordered pores with average pore size of 82nm while templates only resulted in disordered pores in the silica with average pore of  305.86nm.Nanooporous silica was developed from bagasse ash which can be used as catalyst carrier, filtration processes, treatment of effluents etc.
