In this study, the utilization of a coproduct of the bioethanol industry, distiller’s dried grains with solubles (DDGS), was utilized as a base carbon precursor for the formation of a biocarbon material. Variants with and without nitrogen doping using urea were examined to determine the effect on the biocarbon produced and the subsequent effect it had its use as a material in the fabrication of an electrochemical double layer capacitor (EDLC). By incorporating a biobased carbon source in the EDLC, it provides a more sustainable alternative to the petroleum-based carbon black. The physicochemical properties of the undoped and doped DDGS-biocarbon features were evaluated through various techniques including, Raman, X-ray diffraction, scanning electron microscopy, elemental and surface area analyses, among others, to compare and correlate the results obtained. With increased nitrogen content the biocarbon showed an enhanced specific capacitance approximately double that of the undoped biocarbon. This research is beneficial in demonstrating the utilization of a biobased carbon as a potential substitute in the electronics sector by expanding upon the nitrogen doping efficiency and capacitance benefit it provides, showcasing that these under-valued materials can be effective in high-value applications.
