Abstract: Recently, molybdenum disulfide (MoS2) has garnered widespread attention due to its graphene-like structure as well as unique physical and chemical properties, positioning it as a promising material in various fields such as optoelectronics, sensing, catalysis, and lubrication. In order to have a comprehensive understanding of the latest international progress and development trend of molybdenum disulfide, this paper is based on the SCI papers in Web of Science, together with DDA, Excel and subject mining, to conduct bibliometric analysis of literature related to molybdenum disulfide. The analysis dimensions encompass the temporal evolution, geographical distribution, institutional contributions and research hotspots within MoS2 research. The results indicate that the annual number of publications in the field of molybdenum disulfide worldwide has been steadily increasing. The United States leads in the field of molybdenum disulfide, while Singapore is rapidly emerging, and China has a significant advantage in terms of research output scale. Major contributing institutions include the Chinese Academy of Sciences (CAS),Stanford University in the United States, the University of California, Berkeley, and the Singapore Nanyang Technological University in Singapore and the National University of Singapore. Research hotspots primarily encompass 2D materials, electrochemistry, photocatalysts, biosensors and friction and vibration. Finally, this paper puts forward the recommendations to focus on the production of high-quality research, strengthen the international cooperation, and stay abreast of emerging research frontiers.
