Abstract

Graphene-CdS nanocomposites with different CdS contents were synthesized via a solvothermal route. Compared with pure CdS, graphene-CdS composites exhibited higher efficiency in photodegradation of methylene blue (MB) under visible light irradiation. TEM observations demonstrated that a homogeneous distribution of CdS nanoparticles on the graphene nanosheets was formed, while the CdS nanoparticles on graphene-CdS composite (1 g/7.5 mmol) distributed best among graphene-CdS composites. The results show that the graphene-CdS composite (1 g/7.5 mmol) has the highest efficiency and well stability. It demonstrated the mechanism of photodegration was that ˙OH radical generated by graphene-CdS composite plays a vital role by adding dimethyl sulfoxide (DMSO).
