建議看見這篇綜述文獻(xiàn): Graphenes in chemical sensors and biosensors Graphene Exactly one layer of a polycyclic aromatic hydrocarbon network, with all carbon atoms hexagonally arranged in a planar condensed ring system. It has a metallic character and consists solely of carbon and hydrogen. Graphene oxide Exactly one layer of a polycyclic hydrocarbon network, with all carbon atoms hexagonally arranged in a planar condensed ring system. It has various oxygen groups and is partially aromatic. It possesses a band gap greater than 1.5 eV. The band gap depends on its oxidation level. The C:O ratio is between 2 and 3. Reduced graphene oxide (rGO) Exactly one layer of a polycyclic hydrocarbon network, with all carbon atoms hexagonally arranged in a planar condensed ring system. It has an oxygen fraction around or below 10%. It is mostly aromatic and resembles graphene in terms of electrical, thermal and mechanical properties. Graphite “An allotropic form of the element carbon consisting of layers of hexagonally arranged carbon atoms in a planar condensed ring system. The layers are stacked parallel to each other in a three-dimensional crystalline long-range order. There are two allotropic forms with different stacking arrangements, hexagonal and rhombohedral. The chemical bonds within the layers are covalent with sp2 hybridization and with a C-C distance of 141.7 pm. The weak bonds between the layers are metallic with a strength comparable to van der Waals bonding only.” Graphite oxide An heterogeneous material prepared by the oxidation of graphite. It can be described as an assembly of many layers of graphene oxide. We also note an exaggerated use of acronyms in the literature all referring to the same materials, with examples being CRGO, GO, RGO, GR, G, GNS, EG, GNP, CCG, GE, GP, ERGO, GF, EGO, GS, GN, TRGO, CMG, FG, ERGNO, CRGNO, and the like. This allows for a high risk of confusion (e.g. GO may stand for graphite oxide or graphene oxide). In our opinion the words “graphite” and “graphene” are short enough and do not require an acronym. |
