文摘
- •
Ultrathin NiO/NiFe2O4 nanoplates derived from NiFe layered double hydroxides are fabricated on the graphene.
- •
NiO/NiFe2O4 nanoplates on the graphene show superior electrochemical performance compared to pure NiO/NiFe2O4 aggregates.
- •
The effects of the content and the particle size/component of NiO/NiFe2O4 on the electrochemical performances are studied.
- •
Graphene-encapsulated NiO/NiFe2O4 is prepared and shows slightly decreased performance compared to graphene-based composite.
