One-step synthesis of monodisperse palladium nanosphere and their catalytic activity for Suzuki coupling reactions

This paper reports a facile synthesis for monodisperse palladium nanosphere with the diameter of 200 nm in the mixture solution of dimethyl sulfoxide (DMSO) and ethanol without using any other capping agent. It was found that the ratio of DMSO to ethanol is a key parameter in size and shape control. The as-prepared product in this report exhibit prominent catalytic activities in Suzuki coupling reactions and can be reused at least five times without loss of catalytic activity.
