Enhanced electrochemical properties of Ni2+/Fe3+ doped ZnCo2O4/rGO nanocomposite for superior supercapacitor performance

The work reports a Ni 2+ /Fe 3+ co-doped ZnCo 2 O 4 and their composites with reduced graphene oxide for supercapacitor electrodes. The XRD analysis revealed slight peak shifts indicating lattice strain without phase degradation. XPS results confirmed the presence of Zn 2+ , mixe...
