Synthesis of MoS2 nanoflowers on CdS nanorods with a simple route and their application in removal of dyes

CdS@MoS2 nanocomposites (NCs) were successfully prepared through a simple hydrothermal reaction. The morphology and structure of MoS2 nanoflowers on CdS nanorods could be regulated by the change of the mass percentage of MoS2. The adsorption efficiency and photocatalytic activity of CdS@MoS2 NCs were investigated by the adsorption and photocatalytic degradation of Rhodamine 6G. Interestingly, with the increase of MoS2 ratio in the NCs, the adsorption effect of CdS@MoS2 NCs increased significantly. These CdS@MoS2 NCs showed a strong ability to process Rhodamine 6G, and could deal with up to 95% Rhodamine 6G within 1 h.Graphical abstractCdS@MoS2 nanocomposites with tunable shape were synthesized through a hydrothermal method and possess high performance in the removal of Rhodamine 6G
