Abstract
For the first time, we in this study prepared uniform MoS(2 )nanoparticles on ZnO mesoporous. XRD patterns established that the synthesized ZnO and MoS2/ZnO samples were composed of ZnO phase. The TEM results revealed that MoS2 and ZnO were very close to each other, with 4-8 nm in sizes of particles. The MoS2/ZnO nanocomposites have many advantages, and some of these advantages are large surface area (105 m(2)g(-1)) and large pore volume (0.19 cm(3)g(-1)). Foron blue dye degradation over 3 wt% MoS2/ZnO nanocomposite was 254 times larger than that of mesoporous zinc oxide. Also, Foron blue dye degradation over 3 wt% MoS2/ZnO nanocomposite was 1.8 and 1.2 times greater than that of 0.5 wt% MoS2/ZnO and 1 wt% MoS2/ZnO nanocomposite, respectively. The increased Foron blue dye degradation by increase wt% of MoS2, due to increased separation of charge carrier and high capacity of light-harvesting. Moreover, high foron blue dye degradation was due to formation of a heterostructure between ZnO and MoS2, which accelerated charge carrier separation and improved degradation efficiency. The XPS and HRTEM results revealed that the MoS(2)nanoparticles were deposited on the ZnO surface.
