چکیده

Thin-layered materials from the transition-metal dichalcogenide (TMD) family such as MoS2 exhibit great potential as active materials in optoelectronic applications. In this article, we report the synthesis of MoS2 nanostructures by a described chemical method. MoS2 is also of considerable interest due to its high photocatalytic activity. A hybrid -phase system composed of 2H and 1T-MoS2 is a promising two-dimensional (2D) material with a wide range of potential applications. Here, the photocatalytic activities of hybrid prepared MoS2 nanosheets are investigated at different methylene blue (MB) concentrations, pH values, reaction times, and also catalyst doses. Sample characterizations were performed using X-ray diffraction (XRD) analysis, FTIR spectroscopy, UV-Visible spectroscopy and band gap measurements which are discussed in details. The XRD data indicate that a mixture of phases of 1T and 2H- MoS2 was formed. The band gap value of the prepared sample was found to be approximately 1.8 eV confirming monolayer nanosheet synthesized by this method. A high degradation of MB on the MoS2 nanosheet occurs at 98.2%.
