Abstract

Abstract: As a kind of burgeoning carbon nanomaterials,carbon quantum dots have attracted much research attention in recent years,especially those prepared by using natural substances as the origin of carbon. In this review,various synthesis methods of carbon quantum dots were introduced based on the latest research progress,including top-down approach and bottom-up approach. In addition,we summarized the typical characterization methods for carbon dots,such as TEM,Raman spectrum,fluorescence spectrum,ultraviolet-visible spectrum,X-ray diffraction,and nuclear magnetic resonance. The properties of carbon quantum dots and their applications in bioimaging,biological sensing and detection as well as photocatalysis are also introduced. Finally,the future development of carbon quantum dots in photocatalysis and electrocatalysis are forecasted.

Key words: carbon-quantum-dots, synthetic approaches, photoluminescene, bioimaging, photocatalysis
