Nitro compounds derived from industrial and agricultural wastewater due to their solubility and stability in water, are classified as toxic and environmental pollutants. One of the strategies of chemists in combating environmental pollution, is eliminating or reducing pollutants or using wastes as starting materials for preparation of useful chemicals [1]. The reduction of nitro compounds to the corresponding amines which are valuable chemicals in synthetic organic chemistry, is one way to solve this problem [2]. Various nanostructured materials especially nanocomposites have been used as catalysts for the reduction of nitro compounds under mild reaction conditions. Graphene-based nanocomposites due to their high surface area, their extended π-system, and variable functionalities demonstrate optimal features in the field of intended application. On the other hand, 2-D-layered transition metal dichalcogenides like MoS2 is used as one of the most suitable substitutes for rare metals in the catalytic field [3]. So, we designed and synthesized molybdenum-graphene nanocomposites and investigated their catalytic properties on the reduction of some nitro compounds (Fig 1).
