This study presents an eco-friendly approach to fabricating high-performance supercapacitor electrodes using water hyacinth-derived activated carbon (WH), polypyrrole (PPy), and titanium dioxide (TiO2). The WH-TiO2/PPy hybrid electrode was synthesized via hydrothermal treatment and interfacial polymerization, ensuring a resource-efficient and environmentally responsible process. The composite exhibited a high gravimetric capacitance of 610 F g?1 at 0.5 A g?1 in 3 M KOH, with excellent cycling stability (94% retention after 5000 cycles). An asymmetric supercapacitor with WH-TiO2/PPy as the positive electrode and activated carbon as the negative electrode delivered an energy density of 98 W h kg?1 and a power density of 5606 W kg?1. This work highlights the potential of transforming invasive biomass into cost-effective, high-performance energy storage materials, advancing the principles of green chemistry through waste valorization and sustainable material design. 2025 The Royal Society of Chemistry.
