title: Synthesis of MoS2/graphene hybrid supported Au and Ag nanoparticles with multi-functional catalytic properties.
abstract: The detection and removal of nitroaromatic compounds is an important issue for environmental protection. In this study, a hybrid of molybdenum disulfide (MoS2) and graphene (GR) was first synthesized using a facile hydrothermal method. Au and Ag nanoparticles were then deposited onto the surface of the MoS2/GR hybrid with sodium citrate as the stabilizer and reductant. Compared to using pure MoS2as the support, the obtained Au (Ag)-MoS2/GR composites showed improved activity for electrochemical detection and chemical reduction of 4-nitrophenol. The activity enhancement appears to be due to the addition of GR, which could improve the conductivity as well as provide more active sites. The successful synthesis of Au (Ag)-MoS2/GR composites could provide new multi-function catalysts for environmental protection.
