Metal nanoparticle-directed NiCo2O4 nanostructure growth on carbon nanofibers with high capacitance†
Abstract
Metal nanoparticles (Ni, Co) decorated on an electrospun carbon nanofiber surface directed the growth of NiCo2O4 into nanorod and nanosheet morphologies. These metal nanoparticles served as a transition layer to strengthen the interface and promote charge transfer between carbon and NiCo2O4 to achieve a high capacitance of 781 F gā1.
