제목 Synthesis of porous silica nanoparticles from rice husk biomass: A comparison study of synthesis methods
초록 Rice husk is a bulky biomass with a high silica content from rice production. It usually contains around 10% of silica. The utilization of rice husk has been an extensive research topic for decades. However, practical applications of rice husk have been limited to a narrow range of low-value agricultural items, such as fertilizer additives, stockbreeding rugs and bed soil, bcause of their tough and abrasive properites.  
In this study, we investigated the effects of synthesis methods of biosilica from rice husk on silica content, surface area and pore. To obtain high content of biosilica, rice husk was treated with acidics or ionic liquids and burned in a muffle furnace at 800℃ until completely removing all incorporated hydrocarbons. High content of biosilica was found in sulfuric aicd or 1-butyl-3-methylimidazolium hydrogen sulfate treated samples. All biosilica samples obtained this study showed mesoporous structures and high surface-to-volume area.
