Abstract

3–(chloropropyl)triethoxysilane (CPTES) with imidazole and sodium silicate from rice husk ash (RHA) successfully reacted within a short time in one–pot synthesis in purely homogenous method. A similar procedure was used for the immobilization of melamine and saccharine to demonstrate a generally applicable method. No reflux was needed, and a green solvent was used as the reaction medium. The surface areas of the prepared materials were very high compared with the materials which have similar structure prepared by the traditional method. The TGA/DTA confirmed that all the materials were highly stable. The FT-IR shows that all expected the functional groups were present. The HRTEM showed that the materials had ordered mesoporous straight-channels which were like the MCM-41. The synthesis procedure is simple, repeatable with different organic ligands and does not require toxic solvents or multiple steps with high products yield.
