英文摘要:

      Noble metal nanoparticles/carbon quantum dots possesses the merits of both noble metal nanoparticles (AuNPs and AgNPs) and carbon quantum dots(CDs), which has be regraded as a kind of promising functional materials. In recent years, the research on the preparation methods and application of noble metal nanoparticles/carbon quantum dots has gradually increased. AuNPs and AgNPs are widely used in surface enhanced Raman scattering (SERS), sensor, catalysis and antibacterial, etc. Carbon quantum dots are served not only as excellent electron donors, but also as electron acceptors because of the rich functional groups at the surface. What’s more, the preparation process of the noble metal nanoparticles is efficient, environment friendly and controllable, enabling noble metal nanoparticles to be more extensively applied. In this paper, the preparation and application of noble metal nanoparticles/carbon quantum dots in resent years as well as the prospects were summarized.
