Morphological Characteristics Of Molybdenum Disulfide And Current Application On Detecting Sf6 Decomposing Products

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.
