Carbon dots-based composites for catalytical applications
Carbon dots (CDs) have been regarded as a prospective carbon nanomaterials for catalytical applications due to their advantages in low toxicity, strong and broad optical absorption, high chemical stability, and rapid electron transfer properties. To further improve their function, CDs-based composites or hybrid materials have been developed by integrating CDs into different functional nanomaterials such as inorganic nanostructures, biomaterials and polymers and so on. This review presents and discusses the current development of CDs-based composites. After introduction of the methods for the preparation of CDs-based composites, we focus on the description of the factors affecting the synthesis of CDs-based composites. Lastly, the advantages of CDs-based composites in catalytical applications such as photocatalysis, chemical catalysis, peroxidase-like catalysis, fenton-like catalysis and electrocatalysis are described.
