Abstract
CDs (Carbon dots) are a new group of zero-dimensional luminescent
nanomaterials. They have drawn a lot of attention due to their excellent properties, for
example, easy preparation, strong optical properties, low toxicity, significant
biocompatibility, low cost, facile functionalization, tunable porous structures and high
specific surface area. CDs have found many applications in the fields of bioimaging,
sensing, catalysis, optoelectronics and energy conversion. Recently, CDs have
demonstrated promising applications in the control of environmental pollution and
remediation. CDs have been applied for environmental pollutants sensing, adsorption
of contaminants, membrane-based separation, photocatalytic degradation of pollutants,
and antimicrobial coatings for protection. In this chapter, we have discussed the
classification of CDs, synthesis, properties and applications of CDs in environmental
pollution control and environmental protection measures.
