A Rice Husk based nanosilica anchored Ru(III) Schiff-base complex was found to be a very
efficient and reusable heterogeneous catalyst for organic transformation of alcohol to carbonyl
compounds. The catalyst was obtained by simple Schiff-base condensation between 3-aminopropyltriethoxysilane
(APTES) functionalized nanosilica and acetamide. The characterization of the catalyst
was carried out by various techniques such as FT-IR, XRD, ESR, BET surface area measurements,
SEM-EDX mapping and ICP-AES. The alcohol oxidation reactions were performed at 50οC using
acetonitrile and TBHP as solvent and oxidant, respectively. The catalyst was found to be very effective
towards alcohol oxidation with excellent product yield and reusable upto minimum 5th reaction cycle.
Keywords: Alcohol oxidation, heterogeneous catalyst, nanosilica, Ru (III) schiff base, organic, solvent.
