Webb28 jan. 2024 · The diffraction peaks of the compounds, compared with those of PBD, occur at larger degrees. For example, PBD shows diffraction peaks at 2 θ = 9.2° (9.6 Å), while the compounds are at 2 θ = 9.4° (9.4 Å), which demonstrates that compounds have a closer intermolecular staking distance.

WebbXRD pattern is a commonly used tool for separating the compositions and crystallinity of as-prepared graphene materials. Fig. 4.1 shows the XRD patterns of reduced graphene oxide-cellulose nanocrystals-manganese dioxide (rGO–CNC–MnO 2) obtained by in-situ hydrothermal synthesis.Based on the results, it is clear that several sharp diffraction … WebbIt should be mentioned that the XRD profile of the graphite powder obviously shows a high degree of crystallinity, with a strong and sharp diffraction peak at around 26 degrees, which can be assigned to the (002) reflection peak of the graphite. WebbThe Bragg peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter. For protons, α-rays, and other ion rays, the peak occurs immediately before the particles come to rest. It is named after William Henry Bragg, who discovered it in 1903.
