Effects of porous hedgehog-like morphology and graphene oxide on the cycling stability and rate performance of Co3O4/NiO microspheres
{{output}}
A porous hedgehog-like Co3O4/NiO/graphene oxide (denoted as PHCNO/GO) microsphere was prepared by a facile solvothermal method, followed by an annealing treatment under argon atmosphere. Benefiting from the thin Co3O4/NiO nanosheets with a large specific surfa... ...
