Pore-rich graphene networks hold great promise as advanced supporting materials of metals and metal oxides for high electrochemical performance. In this work, a dual substrate-assisted reduction assembly (DSARA) process has been devised demonstrated general approach the spontaneous oxide, well-organized reduced oxide into three-dimensional porous networks, simultaneous functionalization graphenes with metal-based nanocomponents on demand, including metals, oxides, metal/metal hybrids or alloys. The newly designed avoids use toxic reducing agents, multiple steps, long reaction times, offers facile but powerful pathway to greatly enhance merits using pristine in energy-related applications such lithium ion batteries, fuel cells, photoelectric conversion devices, so on. Specifically, an anode material battery (LIB), DSARA-produced RGO decorated NiO/Ni nanohybrids presents record capacity charge–discharge rate compared those reported far Ni based materials. PdPt alloy nanoparticles 3D generated by DSARA exhibits highly efficient catalytic performance oxygen (ORR) cells.
