Synthesis of 3D Na-Embedded Carbon Nanomaterials and Their Applications in Solar Cells

High electrical conductivity and large accessible surface area, which are required for ideal electrode materials in energy devices, are opposed to each other in current materials. In this presentation, I will present you an invented reaction based on Na and CO to synthesize sodium-embedded carbon nanowalls. The synthesized sodium-embedded carbon’s conductivity is two orders of magnitude larger than three-dimensional graphene. Furthermore, the nanowall structure has a large accessible surface area comparable to graphene. This Na-embedded carbon solved the contradiction of high electrical conductivity and large surface area in electrode materials.
