The synthesis of LiNbO3 nanoparticles in SBA-15 is reported for the first time. The preparation of nanoparticles was carried out by impregnation from the metal precursor and mesoporous silica SBA-15 as the template. A rapid one-step treatment in an IR furnace reduces the preparation time to only 10 min. In comparison, a conventional furnace requires 5 h reaction time to produce nanoparticles with similar textural properties. Another advantage of applying an IR furnace compared to conventional heating is the extremely high heating rate (up to 10 oC/s) and corresponding time saving. The resulting samples were investigated by powder X-ray diffraction, nitrogen physisorption, and high resolution transmission electron microscopy (HRTEM). The obtained nanoparticles are spherical with a diameter of approximately 10 nm. © 2011 Grigas and Kaskel; licensee Beilstein-Institut.
