Soncatalytic degradation of organics dyes using cadmium sulfide nanorod molybden disulfide

Fast expansion of nanostructures‟ synthesis methods caused the emergence of different types of developed nanoscale semiconductors. Among the photocatalytic materials used for filtering the organic and inorganic pollutions, we can pinpoint ZnO, Fe2O3, WO3, MoS2, TiO2, and CdS. Nowadays, unique properties of nanoparticles such as high surface to volume ratio and quantum effects have been caused to the increase in the important role of them in some realms, like environment, smell control, sterilization, and renewable energies [1]. MoS2, an important transition-metal dichalcogenide and new emerging excellent adsorbent which composed of three stacked atomic layers (S-Mo-S) held together by Van der Waals force, exhibited unique optical, electronic and chemical properties [2]. In this study CdS/MoS2 nanocomposit was fabricated by sodium molybdate (Na2MoO4), thiourea (S2N4CH) and cadmium nitrate at 200 °C by hydrothermal method. The structure and morphology of the synthesized nanocomposite was characterized by FT–IR, XRD and FE-SEM analysis. The sonocatalytic activity of the synthesized nanocomposite was studied in the presence of H2O2 for degradation of organic pollutants such as Methylene blue (MB), Rhodamine B (RhB) and Methyl orange (MO). Sonocatalytic degradation of all three dyes completely done 20 min.
