Abstract
Novel two-dimensional materials with a layered structure are of special interest for a variety of promising applications. Herein, MoS2 and MoS2/Graphene nanocomposite with hierarchical nanostructure were successfully synthesized employing a one-step hydrothermal method. Photo-degradation of methylene blue (MB) and rhodamine (RHB) were adopted to assess the photo-degradation ability of the products. Comparing with bare MoS2, the hierarchical MoS2/Graphene nanocomposite achieved relatively higher degradation rate of 99% in 28min for MB as well in 50min for RHB. These results verified that this proposed hierarchical nanocomposite is a good photo-degradation semiconductor. The excellent performance was mainly ascribed to the synergistic effect of MoS2 and graphene layers. The MoS2 possessing a band gap of 1.9eV would provide abundant electron-hole pairs. The graphene layers with excellent electro-conductivity could realize the quick transport of electrons via its extended π-conjugation structure, consequently benefiting the separation of photo-generated carriers. These findings indicate that the graphene layer is a promising candidate as a co-catalyst for MoS2 photo-catalyst, and also provide useful information for understanding the observed enhanced photocatalytic mechanism in experiments.
