Sheet-on-sheet like calcium ferrite and graphene nanoplatelets nanocomposite

Calcium ferrite-graphene nanoplatelets nanocomposites with sheet-on-sheet like morphology are fabricated and investigated for their physicochemical characteristics, electrochemical energy storage capacity and photocatalysis. Interestingly, the (CF) (GNPs) nanocomposite-based electrode has shown maxi...
