CdS-Graphene nanocomposite: synthesis, adsorption kinetics and high photocatalytic performance under visible light irradiation

We report an approach for preparation of CdS-graphene nanocomposite via a hydrothermal method. In this process, graphene oxide was reduced to graphene which assists in forming CdS nanoparticles. The adsorption kinetics data is in good agreement with pseudo-second-order kinetic model. Furthermore, the CdS-graphene reveals a high photodegradation rate under visible light irradiation.
