At present, the world faces an unprecedented challenge regarding energy issues. To tackle these issues, there is a growing focus on the advancement of advanced energy storage solutions. This study explores the potential of newly developed nanostructures (NSs) made of iron cobalt sulfide-graphitic carbon nitride (FeCo2S4@g-C3N4) for innovative applications in supercapacitors. The necessary materials were synthesized through the hydrothermal method, ensuring a robust nanostructure foundation. The successful creation of the composite NSs was confirmed through XRD and EDX analysis, verifying both phase purity and compositional consistency. SEM revealed a variety of morphologies, with a unique combination of spherical nanoparticles and sheet-like structures that maximize surface area for enhanced electrochemical interactions. The FeCo2S4@g-C3N4 NS electrode demonstrated impressive electrochemical performance, demonstrating a specific capacitance of 2460 Fg−1 at 1.5 Ag−1, an energy density of 85.4 Whkg−1, and a power density of 375 Wkg−1. This investigation underscores the promise of FeCo2S4@g-C3N4 NS for advanced energy storage solutions, potentially paving the way for next-generation supercapacitors with high energy and power outputs.
