Two-dimensional material heterostructures can effectively combine the advantages of one two-dimensional material with another two-dimensional material or other materials,and have broad application prospects in fields such as catalysis,batteries,sensors,etc.We conducted a bibliometric analysis of Chinese and English literatures related to two-dimensional material heterostructures using Citespace software,and studied the current development status and trends in this field.The research results indicated that the research in this field mainly focused on the properties and applications of heterostructures,including water splitting,degradation,reduction,field-effect transistors,sensors,batteries,and photoluminescence.In recent years,the emerging properties and applications included gas sensors,Raman spectroscopy,surface plasmon resonance,and biaxial strain.The materials in this field involved mainly included two-dimensional materials such as graphene and semiconductor materials such as titanium dioxide.New materials that had emerged in this field included dihydroxy compounds,metal organic frameworks,molybdenum selenide,etc.The synthesis methods mainly relied on epitaxial growth based on chemical vapor deposition.In terms of computation,first principles calculations were the main approach,and molecular dynamics calculations gradually emerged in this field.
