Abstract

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%.
