|제목||Synthesis of Nano Zinc Oxide Immobilized in Rice Husk Silica Nano Particle without Surfactant Assistant|
|초록|| Nanomaterials have used for various field of industry with high reacting surface area caused from their nano-size, which is able to reach the similar effect goal with the less amount of usage than the conventional use. With this property, using the nano-sized material has a product produce an economical advantage. Dispersity, however, of nanomaterial in the compound without surfactant is a difficult task because Van der Waals existing and electrostatic repulsion action on the surface are interfered to form monodisperse.
We proposed synthesis nano zinc oxide dispersed in nanoporous silica produced from rice husk under surfactant-free condition. Silica particle having high absorption property by the high specific surface area was extracted from rice husk ash then synthesized via sol-gel process. Nano zinc oxide was grown from its precursor at the inside of rice husk silica gel to disperse effectively.
