摘要： Increasing complexity of hollow nanostructures, in terms of compositions and architectures, is of vital importance to boost their performance for energy storage. However, controllable synthesis of such exquisite architectures remains a great challenge because of the difficulties with delicate control of chemical reactions on the nanoscale. Starting with metal-organic frameworks, we demonstrate the designed synthesis of complex hollow structures including Co3O4/NiCo2O4 double-shell nanocages, CoSe@carbon nanoboxes with an inhomogeneous shell, and double-shelled hollow structures with CoS-nanoparticle-assembled nanoboxes surrounded by outer CoS-nanosheet-constructed shells. By delicate manipulation of the template-engaged reactions, both the composition and shell structure can be elaborately modulated in desired manners. Because of their compositional and structural advantages, these rational designed materials afford outstanding performance for capacitance energy harvest and reversible lithium storage.
