A fluorescence active catalyst support comprising carbon quantum dots and magnesium oxide doping for stabilization of palladium nanoparticles: Application as a recoverable catalyst for Suzuki reaction in water

Abstract

Novel magnesium oxide-carbon quantum dots are synthesized and used for the formation and stabilization of palladium nanoparticles. This highly water dispersible material, Pd@MgO-CQD, has been used as an active catalyst for Suzuki coupling of aryl bromides at room temperature and aryl chlorides at 80°C in water. Using fluorescence emission of the material, a new protocol for determining Pd loading and leaching in catalyst preparation and recycling process is developed.
