Abstract
We report that sonochemistry is a fast and efficient technique for coating of octadecyltrihydrosilane (CH3(CH2)17SiH3) on titania surfaces. Infrared spectroscopy as well as thermal analysis confirms that complete coating is achieved after 30 min. Solid-state 13C NMR spectroscopy establishes the bonding of trihydrosilane to the titania particles. Raman microscopy gives the expected rutile structure and further confirms the presence of an octadecyl monolayer. X-ray diffraction confirms that the futile structure of the titania particles has not changed during sonication. Anatase titania undergoes the same reaction when sonicated in the presence of octadecyltrihydrosilane.
