Mesoporous ZnCo2O4 nanomaterials grown on a three-dimensional (3D) graphene film (GF) coated on Ni foam (NF) have been synthesized via an effective chemical vapor deposition (CVD) method combined with a subsequent hydrothermal route.
A Si@Ni inverse opal structure fabricated by using an inexpensive electrodeposition method and a colloidal crystal template exhibits high capacity, cyclability, and rate-performance as an anode for Li ion batteries.
