Preparation, Characterization, and Catalytic Properties of Pd-Graphene Quantum Dot Catalysts

In this study, Pd-graphene quantum dot (Pd-GQD) catalysts were prepared by depositing Pd nanoparticles onto functionalized GQD surfaces, and their morphology elemental composition characterized using transmission electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy. The as-prepared Pd-GQD was subsequently employed as a catalyst for the Heck decarboxylative cross-coupling reactions found to exhibit higher catalytic activity than other reference systems. expanded substrate scope of various substituted aryl iodides further proved that is an effective support preparing new heterogeneous with improved performances.
