Hydrothermal Synthesis of MoS2/rGO Heterostructures for Photocatalytic Degradation of Rhodamine B under Visible Light

MoS2/rGO composites were synthesized by hydrothermal method from the precursors of MoS2 and reduced graphene oxide (rGO) prepared in former steps. The influence synthesis conditions including temperature mass ratio to rGO on structure, morphology, optical absorption capacity was systematically investigated using physicochemical characterizations. photocatalytic performance as-prepared samples degradation Rhodamine B under visible light, which, obtained at 180°C 4/1 exhibited highest photodegradation efficiency approx. 80% after 4 hours reaction. This enhancement behaviour could be assigned positive effect life time expansion photoinduced electrons—holes.
