Abstract In this study, waste tire‐derived activated carbon (WTAC) was applied in dye adsorption and energy storage. The thermal decomposition temperature of WTAC was also investigated. The characterization of WTAC was analyzed through modern analytical methods of scanning electron microscopy, Raman spectroscopy, X‐ray powder diffraction, energy‐dispersive X‐ray spectroscopy, and Fourier transform infrared spectroscopy. Besides, the effects of the adsorption time, crystal violet concentration, and WTAC mass on the adsorption capacity were evaluated. As a result, WTAC showed great ability with an adsorption capacity of up to 39.2 mg/g and a specific capacitance of 311 F/g. In addition, the synthesis of aerogel from WTAC achieved a conductivity of 0.06 W/mK, which shows the potential in replacing insulation materials at the moment.
