Study of Sonication Assisted Synthesis of Molybdenum Disulfide (MoS2) Nanosheets

Abstract Herein, we report the two separate processes of MoS2 synthesis via sonication assisted liquid phase technique. The first process involves bath sonication of bulk MoS2 dissolved in NMP for five hours followed by centrifugation. In addition to the bath sonication, the second process involves probe sonication for two hours at room temperature. A comparative characterization study of the exfoliated MoS2 nanosheets is performed by UV-Vis, photoluminescence (PL), and Raman analysis. The morphological structure was analyzed using FESEM. The synthesized MoS2 are well dispersed and can be explored for bio-sensing applications. These two reported techniques are simple, rapid, cost-effective and without the involvement of complex systems
