Abstract A novel molybdenum disulfide (MoS 2 ) and graphitic carbon nitride (g-C 3 N 4 ) composite photocatalyst was synthesized using a low temperature hydrothermal method. MoS 2 nanoparticles formed on g-C 3 N 4 nanosheets greatly enhanced the photocatalytic activity of g-C 3 N 4 . The photocatalyst was tested for the degradation of methyl orange (MO) under simulated solar light. Composite 3.0 wt.% MoS 2 /g-C 3 N 4 showed the highest photocatalytic activity for MO decomposition. MoS 2 nanoparticles can increase the interfacial charge transfer and thus prevent the recombination of photo-generated electron–hole pairs. The novel MoS 2 /g-C 3 N 4 composite is therefore shown as a promising catalyst for photocatalytic degradation of organic pollutants using solar energy.
