Fig. 4: CV analysis of GCE coated with MXene, ZIF-8 and composites MXOF.

CV cycles of MXene (a), ZIF-8 (b), and MXOF (c) demonstrate electrochemical behaviour. Corresponding plots of anodic and cathodic peak currents for MXene (d), ZIF-8 (e), and MXOF (f), reflecting improved charge transfer and electroactivity in the composite material.
