Two-dimensional (2D) nanomaterials are composed of thin layers that may have a thickness of at least one atomic layer. Contrary to bulk materials, these nanomaterials have a high aspect ratio (surface-area-to-volume ratio) and therefore have many atoms on their surface. These atoms have a different function than internal atoms, and so the increase in the number of surface atoms leads to a change in the behavior of 2D nanomaterials. Graphene, as one of the most widely used and most important 2D materials, has unique properties that result in its widespread use in various industries. After successful performance of graphene in many applications and industry, it is expected that other two-dimensional materials will also have this capability. However, the use of other two-dimensional materials requires more time and effort.
