Description 1321-1326
Pt and Ru nanoparticles are deposited on carbon nanotubes via a simple wet impregnation method using aqueous solutions of platinum and ruthenium salts to prepare the supported catalysts of Pt/CNTs (nominal load 5 wt%) and Ru/CNTs (nominal load 10 wt%). The catalysts are characterized by XRD, XPS, BET and TEM data and tested for the hydrogenation of aldehyde and substituted acetophenoneusing pure water as the sole solvent. The reaction conditions are well optimized through the hydrogenation of <em>p</em>-methoxybenzaldehyde and acetophenone. These catalysts exhibit high activity for the hydrogenation of aldehydes and ketones. Many aldehydes and ketones can be efficiently convertedto the corresponding alcohols in the presence of Pt/CNTs and Ru/CNTs. The use of water as solvent makes this catalytic system environmental-friendly.
