Name: Porous graphene
Product Overview
Porous graphene, while retaining its inherent advantages, exhibits a series of new properties due to the presence of nanoscale pores. Firstly, its pores significantly improve the efficiency of material transport, just like opening countless high-speed channels on the two-dimensional plane of graphene. The atomic level pores demonstrate excellent sieving ability, which can accurately separate ions and molecules of different sizes. This sieving effect has great potential for applications in seawater desalination, ion separation, and other fields.
In addition, the introduction of pores has a crucial impact on the band structure of graphene. The band gap that was originally difficult to achieve in graphene is effectively opened due to the presence of pores. This breakthrough is crucial for the application of graphene in the field of electronic devices, enabling porous graphene to play a greater role in transistors, integrated circuits, and other areas, providing new possibilities for the development of high-performance electronic devices.
In graphene, the ideal arrangement of carbon atoms is a hexagonal ring structure. Therefore, cutting graphene into nanomaterial GNR with a certain width and quasi one dimension can obtain two different types of edge structures - armrest and sawtooth. Graphene with serrated edges is usually metallic, while those with armrest edges may be either metallic or semiconductor, depending on the width of the nanobelt. In fact, the edges of graphene nanosheets are irregular and do not strictly adhere to the two types of edge structures. Because sp2 hybridization can arrange carbon atoms into different polygonal structures, non hexagonal ring structures may occur as long as specific symmetry rules are met. Moreover, slight structural changes will result in no difference in conductor properties between the two edge types of graphene. In porous graphene, these two edge structures coexist, so the electronic structure of porous graphene can be determined not only by the type of its edges, but also by the number of active edges. However, due to the periodicity and inconsistent neck width of PG nanopores, as well as the different shapes and edge morphologies of each pore, their electrical properties exhibit more complex behavior.
