Abstract

The designed synthesis of advanced nanocomposite architecture is significant for its applications in energy storage, catalysis, sensing, etc. Herein, thin Al₂O₃ hexagonal nanosheets with encapsulated hollow Co₃O₄ nanoparticles (Co₃O₄-HNPs) are successfully synthesized by using Co₆Al₂CO₃(OH)₁₆·4H₂O nanosheets as templates followed by a two-step annealing process. When used as an anode material in lithium ion batteries (LIBs), the homogeneous Co₃O₄-HNP/Al₂O₃ nanosheet composite exhibits an excellent performance with high reversible capacity and rate capability, and enhanced cycling stability.
