Catalytic templating approaches for three-dimensional hollow carbon/graphene oxide nano-architectures

摘要

We report a catalytic templating method to synthesize well-controlled three-dimensional carbon nano-architectures. Depending on graphene oxide content, the morphology can be systematically tuned from layered composites to 3D hollow structures to micropo-rous materials. The composites with high surface area and high porosity induce a significant enhancement to its capacitance at high current density.
