Sugarcane bagasse is a well-known agricultural residue produced in high quantities around the world and Sugarcane Bagasse Ash (SCBA) is one another waste generated in tonnes as a result of consumption process which is mostly dumped as landfills. These wastes generated out of Sugarcane industry are enriched with silica content and are ecologically safe and biocompatible. The present study was focused on extracting silica from sugarcane bagasse and to synthesize mesoporous silica using sol-technique. The synthesis of mesoporous silica nanoparticles from sugarcane bagasse fly ash involved liquid crystal templating mechanism. Initially, the Sugarcane Bagasse Fly ash extract and HCl concentrate was taken in the ratio of 1:10, to which 1:6 ratio of Sodium hydroxide was added to obtain base solution of sodium silicate wherein H2SO4 concentrate solution was put in along with a non-ionic surfactant, polyethylene glycol (PEG) to obtain a white colour precipitate followed by the process of gel formation. The PEG used as surfactant template was then removed through heat treatment using muffle furnace. The resultant mesoporous silica biomaterial synthesized from sugarcane bagasse ash, was characterized with very high surface area that could relatively encapsulate number of bioactive molecules of interest involving eco-friendly techniques.
