One-pot electrochemical synthesis of palladium nanoparticles and their application in the Suzuki reaction

A novel potential controllable, template free, electrodeposition/synthesis of palladium nanoparticles on an electrode surface as well as in the bulk electrolyte using ionic liquid as an electrolyte cum stabilizer is reported for the first time. The present method of preparation of palladium nanoparticles is advantageous as it eliminates the requirement of additional stabilizers or capping agents. The prepared palladium nanoparticles are characterized by different techniques such as TEM, SEM, EDAX and XPS analyses. These nanoparticles exhibited high catalytic activity for the Suzuki coupling reaction of unactivated halides in aqueous media with high TON.
