Description
In this study, a graphitic carbon nitride/Cobalt oxide/Polyaniline (g-C3N4/Co3O4/PANI) ternary nanocomposite was synthesized through an integrated approach combining a simple hydrothermal method with in-situ oxidative polymerization. The binary g-C3N4/Co3O4 and g-C3N4/PANI hybrid composites were also synthesized to elucidate the synergistic effects of the individual components. The structural and morphological analysis confirms the successful formation of binary and ternary composites. The porous architecture of g-C3N4/Co3O4/PANI nanocomposite synergistically combines the pseudocapacitive contributions of Co3O4, the conductive pathways of PANI, and the stabilizing role of g-C3N4, resulting in enhanced surface accessibility and improved electrolyte wettability. Strong interfacial interactions, including ?-? conjugation between g-C3N4 and PANI with Co3O4 induced electrostatic stabilization, ensuring considerable mechanical robustness. Electrochemical assessments reveal that the g-C3N4/Co3O4/PANI composite showcased a remarkable specific capacitance of 1152 F g?1 and 93 % capacitance retention over 5000 galvanostatic charge-discharge cycles. The configured asymmetric supercapacitor (g-C3N4/Co3O4/PANI//activated carbon) delivers superior energy and power densities of 59.1 Wh kg?1 and 2693 W kg?1, respectively. The developed nanocomposite represents a significant advancement in hybrid electrode materials, offering substantial potential for next-generation high-performance energy storage systems. 2025 Elsevier Ltd
