Preparation and characterization of m-phenylenediamine carbon quantum dots
ABSTRACT
Nanomaterials have become a research hotspot in the field of materials science because of their unique physicochemical and optical properties. Among them, carbon nanomaterials have become one of the most promising nanomaterials in green nanotechnology. Carbon nanomaterials are widely used in the fields of nano-electronics, optics, catalytic chemistry, biomedicine and sensors due to their diverse forms, excellent electrical conductivity, good biocompatibility, stable chemical properties and large specific surface area. As a new zero-dimensional material, carbon quantum dots are favored because of their unique low toxicity, optical stability and environmental friendliness. In this paper, phenylenediamine was selected as carbon source, and the most suitable synthesis method was found by studying different synthesis methods of carbon quantum dots. Then the optical characterization method was used to verify the existence of carbon quantum dots. Finally, the future applications of carbon quantum dots are prospected.
