Abstract:

Carbon dot(CD) is a kind of environmental friendly nanoparticles that have attracted much interests in the field of photoelectric materials, catalysis and biomedicine, etc. As a novel kind of CDs, carbonized polymer dots(CPDs) possess lots of active sites, controllable conjugated structure and good compatibility, showing great potential. In this review, the synthetic approaches and characterization ways are summarized, including how to establish the relationship between precursor structure, micro-nano structure of CPDs as well as their properties through introducing hybrid atoms, and tuning the groups and active sites, as well as defects on the surface of CPDs, the carbonized procedure, crystal structure, conjugated degree and energy levels. The applications of the CPDs and their hybrid and composites in photo(electro) catalysis, photo-electric conversion and energy storage are introduced. At last, the issues to be addressed and the prospective of carbon dots are proposed.

Key words: Carbonized polymer dots, Structure-function relationship, Carbon dots
