제목 Heteroatoms-doped Graphene Quantum Dots for Visible Light-driven Aerobic Oxidative Coupling Reactions of Amines
초록 Nitrogen-doped or nitrogen, and sulfur-codoped graphene quantum dots (N-GQDs, or NS-GQDs) were synthesized by using norepinephrine as a precursor in water or DMSO under microwave irradiation. It was found that NS-GQDs exhibited greater optical properties, including enhanced absorption in visible range, intense fluorescence with a quantum yield of 17%, and longer lifetime, than N-GQDs. Finally, as-prepared NS-GQDs successfully performed the outstanding photocatalytic activity for the oxidative coupling reactions of various aryl amines under visible light irradiation. The photocatalytic reaction mechanism of oxidative coupling of aryl amines was fully investigated.
