WebDec 26, 2024 · To analyse few-layer graphene samples, we considered the three bands, i.e., D, G, and 2D, of Raman spectra. At 1300 °C, the P10% Fe sample resulted in fewer defects than the other catalyst percentages sample. ... The interlayer distance (d 002) values for the P2% to P20% Fe samples were in the range of 0.3357–0.3366 nm, which … WebDec 16, 2024 · The interlayer distance between two graphene layers is 2.73 Å for Gra-C(111)/Gra-C(111) under the pressure of 20 GPa, which is larger than the interlayer space about 1 Å in H–C(111)/H–C(111) system. It is obvious that large interlayer separation can avoid interlayer interaction effectively. In Gra-C(111) ...
WebDue to the presence of oxygen-containing functional groups between the graphene layers, the assembled film could form 2D nanochannels. In addition, those functional groups on the surface of GO allow the solvent and ions to intercalate into the channels, resulting in a varied interlayer distance [28,29,30].
