Description
Summary:[Display omitted] •Activated carbon was synthesized from Wisteria sinensis biomass.•The activated carbon possesses a large surface area with a mesoporous structure.•The activated carbon electrode delivered higher specific capacitance in acidic electrolyte compared to the neutral electrolyte. Herein, we proposed, for the first time, a novel activated carbon (AC) material synthesized from Wisteria sinensis (WS) seeds biomass. Characterizations of the material were carried out by Field-emission scanning electron microscopy, Transmission electron microscopy, X-ray diffraction, Raman spectroscopy, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller specific surface area analysis. As-synthesized AC was employed as an electrode material to evaluate its applicability in energy storage devices. Results showed enhanced capacitive performance in an acidic electrolyte compared to the neutral electrolyte at similar current density. Thus, as-synthesized AC could be a suitable material for energy storage applications.
