Abstract:
In October 2023, the Nobel Prize in Chemistry was awarded for the discovery and synthesis of quantum dots. In recent years, research on graphene quantum dots (GQDs) has received widespread attention in carbon materials, and functional GQDs will represent a new generation of GQDs and play a key role in various application fields. In addition to its advantages such as environmental friendliness, higher chemical stability, and superior electron conduction, it also has some advantages as a semiconductor material, such as strong visible light absorption and good photostability. However, the current preparation of GQDs faces issues of cumbersome synthesis methods and insufficient configuration control, and the impact of surface functional groups on their application performance is still unclear. Our team focuses on the controllable preparation, optical properties, and surface/interface regulation of zero-dimensional GQDs. We have not only developed various groundbreaking synthesis strategies for GQDs but also pointed out the importance of large-scale solution growth for single-crystal and single-atomic-layer graphene materials. Furthermore, they have applied graphene GQDs and their composite nanomaterials to fields such as environmental green catalysis, white light high-performance light-emitting devices, and biology.
