A ZnWO4/g-C3N4 heterostructure electrode was synthesized and evaluated for advanced electrochemical energy-storage and photocatalytic applications. The formation of a heterojunction between ZnWO4 and graphitic carbon nitride significantly enhances ion transport, electronic conductivity and electroactive surface accessibility. Structural and spectroscopic analyses were suggesting strong integration of ZnWO4 and g-C3N4 within the nanocomposite material. Electrochemical investigations demonstrate an exceptionally high specific capacitance of 2225 F g−1 for the ZnWO4/g-C3N4 electrode, markedly surpassing then pure ZnWO4 876 F g− 1, along with excellent rate capability. Kinetic analysis based on cyclic voltammetry reveals that surface-controlled capacitive processes contribute to charge storage, contributing approximately 64–69% of the total capacitance, indicative of rapid ion diffusion and efficient charge-transfer dynamics. Electrochemical impedance spectroscopy further confirms enhanced electrolyte-electrode interaction in the heterostructure. In addition, the ZnWO4/g-C3N4 composite exhibits improved visible-light-driven photocatalytic degradation of organic pollutants (85% within 60 min), suggesting improved charge separation at the heterointerface. The synergistic enhancement of ionics, pseudocapacitive behaviour, and charge-transfer kinetics highlights ZnWO4/g-C3N4 as a promising electrode material for high-performance supercapacitors and multifunctional electrochemical systems.
