摘要

Pt NPs CO-operate: Pt nanorods (Pt NRs) have been developed by the self-assembly of uniformly distributed small Pt nanoparticles (Pt NPs, 1.8-2.4 nm), obtained from [Pt(cod)Cl _2] (cod=1,5-cyclooctadiene) in the presence of CO in non-aqueous medium. As-synthesized non-supported Pt NRs catalyze the asymmetric hydrogenation of methyl pyruvate and acetophenone to (R)-methyl lactate and (R)-1-phenyl ethanol, respectively (see scheme).
