| Sumario: | 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 maximum specific capacitance up to 422 Fg¯¹ at 0.25 Ag¯¹ with excellent cycling stability, 2.6 times higher than that of neat CF nanosheets. Furthermore, the synergistic contribution from photocatalytic and photo-Fenton reactions enables (CF) (GNPs) nanocomposites to offer superior photocatalytic activity (99.4% dye removal in 90 min). The inclusion of GNPs significantly enhances the charge carriers separation and transportation. The excellent electrochemical efficiency of (CF) (GNPs) could be attributed to the 2D interfacial interactions that provide a better charge transport at electrode/electrolyte interface. These interactions are also responsible for creating effective charge transport pathways and efficient e/h separation leading to rapid dye-degradation, which make the material potential for remediation of water pollution and energy storage systems. |
