Abstract
Graphene oxide (GO)-supported nickel ferrite (NiFe2O4) nanoparticles were prepared via the chemical co-precipitation technique. The resulting pure NiFe2O4 and NiFe2O4/GO nanocomposites display an inverse cubic spinel structure with binary interstice occupancy according to experimental and density functional theory (DFT) simulations. The structural-dependent physiochemical variations reflect in the narrow bandgap of GO-coupled NiFe2O4 with a distinct structural landscape. The narrow optical bandgap of the resultant GO-NiFe2O4 (1.48 eV) nanoferrite illustrates their potential utility as a promising photocatalyst with active charge separation.
