摘要：

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 MoS2 as 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.
