文摘

Graphene nanocapsules (GNCs) are made by ZnO template via forming oxygen bridges. GNCs feature 3D interconnected networks and abundant hierarchical short pores. The GNC electrodes show high capacitance, good rate performance and cycle stability. This approach provides a novel pathway for mass production of 3D graphene materials.
