Figure 2: Structure characterization and phase analysis of composite powders.
From: Graphene-copper composite with micro-layered grains and ultrahigh strength
(a) XRD patterns of composite powders after freeze drying, drying in vacuum and reduction in H2, (b) FTIR spectra of GO before and after Cu2+ ions are added, (c) Proposed mechanism for the epoxide ring-opening reaction assisted by Cu2+ ion, (d) C1s XPS spectrum of GO-CuO composite powder, and (e) C1s XPS spectrum of RGO-Cu composite.
