Effect of modified graphene quantum dots on photocatalytic degradation property

A novel property of graphene quantum dots (GQDs) as efficient nanomaterials for degradation of organic pollutant dyes (methylene blue, MB) under visible light irradiation is found. Moreover, the degradation rate could be qualitatively controlled by using different polymer-modified GQDs. Also, the degradation mechanism is discussed. Thus, photocatalytic organic matter degradation, sustained drug release, and tracking can be combined to implement proper sewage disposal.93
