چکیده مقاله:
In present study, a facile method was used to synthesis noble metal nanoparticles on Ni modified MoS2 (MNi/MoS2 (M = Au and Pt). The morphology and structure of prepared products were detected using different microscopic and spectroscopic methods. The as-synthesized MNi/MoS2 nanocomposites were applied for catalytic reduction of p-nitrophenol in the presence of NaBH4. The obtained catalytic results indicate that noble metal nanoparticles significantly affect catalytic performance of MoS2. Synergistic effect between metal NPs and MoS2 was introduced as the origin of this improved catalytic activity of metals decorated MoS2 particles. The enhanced catalytic activity of Ni modified MoS2 particles in comparison to that of unmodified MoS2 nanocomposites emphasis on the role of Ni in catalytic efficiency. Nitroaromatic compounds as one of the most prevalent contaminants in industrial and agricultural effluent are hazardous and resistant to natural degradation in the environment. Removing of nitro groups through the catalytic reduction of these compounds in the presence of a reducing agent is an effective solution to decrease their toxicity.
