X-ray diffraction (XRD) patterns of GO, rGO, AgNPs, and rGO-AgNP nanocomposites.

Notes: (A) In the XRD pattern of GO, a strong sharp peak at 2θ=11.7° corresponded to an interlayer distance of 7.6 Å. (B) rGO had a broad peak centered at 2θ=25.88°, corresponding to an interlayer distance of 3.6 Å. Apart from the characteristic reflections of rGO (2θ=25.88°). (C) AgNPs showed distinct reflections in the diffractogram at 32.8°, corresponding to the (111) planes. (D) rGO-AgNPs showed two different distinct reflections in the diffractogram at 25.88°, corresponding to rGO, and 32.8°, corresponding to the (111) planes of face-centered cubic Ag. At least three independent experiments were performed for each sample, and reproducible results were obtained. The data show the results of a representative experiment.

Abbreviations: rGO, reduced graphene oxide; NPs, nanoparticles.
