The project intends to design and synthesize efficient broad-spectrum light-harvesting materials based on new environmental-friendly graphene quantum dots. First, highly efficient broad-spectrum responsive graphene quantum dots are low-cost, high-quality macro-controllable prepared in Fig.1.[1,2] Second, grapheme quantum dot nano-compounds are prepared using various metal compounds.[3,4] The photocatalytic performances of grapheme quantum dot nano-compounds are regulated due to the broad-spectrum and electron transfer characteristics of graphene quantum dots. Last, the separation and dominant mechanisms of photo-generated electrons and holes in photocatalytic reaction process are discussed.[3,4] The researches provide a theoretical guidance for the design and synthesis of nano-photocatalyst in the future, but also expect to be important applications in the degradation of pollutants and artificial photosynthesis for water-splitting.
