In this work, we demonstrated an accessible and facile method to prepare hierarchically porous carbon (HPC)/Co3O4 nanocomposites (HPCC). Biomaterials-derived HPC was used as the appropriate carrier to load Co3O4 nanoparticles due to its hierarchically porous structure and high surface area of 163 m2 g−1. The HPCC nanocomposites were used as an anode material for lithium-ion batteries (LIBs) and showed...
Novel porous cage-like carbon (C)/nano-Si nanocomposites as anode materials for lithium-ion batteries (LIBs) was prepared based on nano-Si@zeolitic imidazolate frameworks (ZIF-8)-templated method. In this strategy, p-aminobenzoic acid was initially grafted onto nano-Si to form benzoic acid-functionalized nano-Si, and then nano-Si@ZIF-8 was constructed by alternately growing Zn(NO3)2·6H2O and 2-methylimidazolate...
