摘　　要：PEG-stabilized platinum nanoparticles with uniform size were prepared successfully. They did not precipitate after being stored for four months. The nanoparticles show high catalytic activity for hydrogenation of styrene and selectivity of long chain olefins. The platinum nanoparticles modified by cinchonidine give 85.6% e.e selectivity in asymmetric hydrogenation of ethyl pyruvate.PEG-stabilized platinum nanoparticles with uniform size were prepared successfully.
