Implanting N-doped CQDs into rGO aerogels with diversified applications in microwave absorption and wastewater treatment

In this work, water-soluble nitrogen-doped carbon quantum dots (N-CQDs) were synthesized by a one-step hydrothermal method, and then implanted into graphene aerogels to obtain N-CQDs/rGO composites. Herein, N-CQDs, as connection sites and channels in rGO, can effectively promote electron jumping and migration and greatly enhance the conduction loss of rGO. As expected, the composites exhibit excellent microwave absorption performance with...
