摘要

Linear polystyrene-stabilized Pt nanoparticles were prepared using phenylboronic acid and NaBH₄ as the reductant. The size of Pt nanoparticles was dependent on the reductant, while the immobilization degree of Pt was not. The resultant polystyrene-stabilized Pt nanoparticles showed high catalytic activity for aerobic alcohol oxidation in water and hydrogen-transfer reduction of olefin, ketone, and nitro group using 2-propanol as a hydrogen donor. The catalyst was recycled without significant loss of activity.
