摘要：

Ru nanoparticles were successfully supported on molecular sieves and it was further characterized by sophisticated analytical methods such as transmission electron microscopy, energy-dispersive X-ray spectroscopy and nitrogen adsorption techniques. Transmission electron microscopy data confirmed, indicated the formation of metal oxide nanoparticles (4.5 +/- 2 nm) on the external surface of molecular sieves. Ru supported molecular sieves were applied as a catalyst for the hydrogenation of carbonyl compounds. Aldehydes as well as ketones were successfully hydrogenated in good yield and selectivity. Easy synthesis of air/moisture stable catalyst, hassle free reaction protocol (no requirement of aqueous work-up), 7 times catalyst recycling and additive free approach were the promising outcomes of the proposed work.
