Summary: This article reports on the characteristic dual-domain structures of reduced graphene oxide (rGO) layers and their application as electrode materials in energy storage systems. Conductive atomic force microscopy (CAFM) technique reveals that the rGO surface consists of a graphene and graphene oxide (GO) dual-domain structure, providing electric-electrolyte pathways to the electrode. The quantity, configuration, and connectivity of these domains depend on the reduction level of rGO. The rGO sheets with well-connected and balanced dual-domain composite structures exhibit higher specific capacitance. Additionally, hybrid composite sheets of Fe2O3@rGO and MnO2@rGO were fabricated and examined for further enhancing specific capacitance using the concept of a triple-phase boundary (TPB) where the pseudo-type ceramic particle and the dual-domains coincide. The reduction mechanism of rGO layers and the formation behavior of freestanding rGO sheets from rGO suspension were also discussed in this study.
