Abstract:

Carbon quantum dots(CQDs) as a new member of the family of carbon nanomaterials, have excellent fluorescence properties, biocompatibility and weak cytotoxicity, and have attracted wide interests of scientists. In this paper, the preparation methods of CQDs were introduced. The advantages and disadvantages of these methods and their effect on the composition, structure and properties of CQDs were discussed. In view of optical and electrochemical properties of CQDs, the application of CQDs in the field of energy and environment was summarized. In addition, some challenges in the process of CQDs research were analyzed. Several recommendations and opinions were provided for the further research in CQDs, which will provide important reference for the development of CQDs applications.

Key words: carbon quantum dots, nanomaterials, preparation methods, energy and environment
