Catalytic properties of palygorskite supported Ru and Pd for efficient oxidation of alcohols

• Natural abundant palygorskite as support
• Excellent catalytic activity for oxidation of alcohols
• Wide application scopes of alcohols
• Promising recyclability

Natural palygorskite (PG) was employed to prepare cost-effective, reusable supported catalyst of Pd/PG and Ru/PG through wet impregnation method. The catalysts were characterized through AFM, ICP-AES, XPS, XRD, BET, TEM and FTIR. The catalytic properties of the synthesized catalysts were assessed and optimized through oxidation of alcohols with PhIO as oxidant. It showed that the existence of Ru and Pd in the catalysts dramatically enhanced the catalytic activity with a prominent selectivity of far more than 99% compared with the palygorskite.

Palygorskite (PG) Supported Ru (Ru/PG) and Pd (Pd/PG) catalysts were prepared. Excellent catalytic performance achieved in the oxidation of alcohols with PhIO as oxidant.Figure optionsDownload as PowerPoint slide
