Unveiling the sensing ability of new MoS2 nanoparticles: from fundamental insights into practical applications for nitrites

Abstract

The unique properties of transition metal dichalcogenides (TMDs), particularly molybdenum disulfide (MoS₂), have garnered significant attention in various fields including electronics, catalysis, and energy storage. The synthesis of MoS₂, along with controlled morphology and properties, remains a crucial aspect because of its practical applications. Here, we present an alternative synthesis approach for MoS₂, obtained by a solvothermal method, starting from bis(acetylacetonato)dioxomolybdenum(VI), MoO₂(acac)₂. Our method results in the formation of a carbon MoS₂ (∼75% : ∼25%) composite material. This composite holds promise for advancing our understanding and utilization of MoS₂ for sensing. Through detailed characterization and analysis, we elucidate the structure and morphology of the synthesized MoS₂, and provide insights into its sensing applications for nitrites. This study not only contributes to the synthesis methodology of MoS₂—it also offers valuable insights for the design and development of advanced TMD-based materials.
