One-step syntheses of MoS2/graphitic carbon composites with enhanced photocatalytic activity under visible light irradiation

This paper presents a facile one-step approach for the syntheses of MoS2/GC (GC = graphitic carbon) with sodium alginate as the biomass carbon source. The MoS2/GC composites showed enhanced photocatalytic activity for degradation of methylene blue under visible light irradiation. The MoS2/GC (2 : 1) composite shows the best performance and 99.2% methylene blue can be removed in 100 minutes. GC plays an important role in the fast separation and transfer of photogenerated charges across interfaces. The activity and stability performances suggest that the MoS2/GC composite has great potential for practical industrial wastewater treatment.
