Özet

In this study, a high-surface-area carbon material (MW) was prepared from waste marine sponge using the pyrolysis technique, and its structural, morphological, and electrochemical properties were comprehensively characterized and elucidated. The resulting sustainable material was, for the first time, evaluated and investigated in supercapacitor applications by being modified onto the surface of both glassy carbon (GC) and boron-doped diamond (BDD) electrodes. Characterizations carried out by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and BET surface area analysis (Brunauer–Emmett–Teller) showed that MW has a semi-amorphous, porous structure containing heteroatoms (O, N). Furthermore, the specific surface area of 519.82 m2g−1 and oxygen/nitrogen groups on the surface contributed to ion storage and pseudocapacitive behavior. In electrochemical tests, cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) were used. The BDD electrode demonstrated superior performance, with a specific capacitance of 287.33 Fg−1, while the GC electrode exhibited a lower charge transfer resistance (Rct = 124.43 Ω). The results supported the promising use of waste-derived carbon material in sustainable energy storage systems and the significant relationship between electrode type and performance.
