MoS₂ has been considered a potential novel material in various fields due to its large specific surface area, high carrier mobility, and tunable electronic properties. However, with the increasing demand for sensor substrates, different strategies have been made to achieve its high performance, usually by adopting the method of controlling the microstructure. SF₆ gas-insulated electrical equipment has gained considerable attention in electric systems with the advantages of small volume, high security, strong breaking performance, and high-pressure fracture tolerance. Nevertheless, in the process of equipment operation, the SF₆ gas will occur inevitably decompose due to partial discharge, resulting in the deterioration of the insulation performance of the equipment. Therefore, detecting SF₆ decomposition products is significant for the safe and stable operation of power systems. In this mini review, we start from the synthesis of various MoS₂ morphological structures. Then, the beneficial characteristics of the unique synthesized nanostructures at present are analyzed. Besides, we focus on the gas-sensing mechanisms and applications of MoS₂-based sensors for detecting SF₆ decomposition products. Finally, the future development in this field is proposed.

MoS ₂由于其大的比表面积，高的载流子迁移率和可调节的电子特性，已被认为是各种领域中潜在的新型材料。然而，随着对传感器基板的需求的增加，通常通过采用控制微结构的方法，已经采取了不同的策略来实现其高性能。SF ₆气体绝缘电气设备具有体积小，安全性高，断裂性能强和耐高压断裂的优点，因此在电气系统中受到了广泛的关注。尽管如此，在设备运行过程中，SF ₆气体会因局部放电而不可避免地分解，从而导致设备绝缘性能下降。因此，检测SF ₆分解产物对于电力系统的安全稳定运行具有重要意义。在这个小型综述中，我们从合成各种MoS ₂形态结构开始。然后，分析了目前独特的合成纳米结构的有益特性。此外，我们专注于基于MoS ₂的传感器的气体传感机制及其在检测SF ₆分解产物中的应用。最后，提出了该领域的未来发展。
