title: Unique synthesis of hollow Co3O4 nanoparticles embedded in thin Al2O3 nanosheets for enhanced lithium storage.
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.
