Activated carbon prepared from locally available bio-resources and wastes could be considered eco-friendly, low-cost, and sustainable materials for energy and environmental applications. In this paper, we introduced an eco-friendly method to prepare high surface area activated carbon microfibers from discarded paper. The pristine paper was used for the separator in the supercapacitor whereas activated and carbonized paper (ACP) was used as both positive and negative electrodes in the supercapacitor. The ACP was obtained by simple carbonization and KOH-activation methods. Flexibility, free-standing nature, and high porosity were the main features of the as-prepared ACP. The product was studied with various analysis techniques. Overall, this study demonstrated an effective protocol for the synthesis of activated carbon from waste. We believe that this strategy can be used for other bio-based waste materials in the future for energy and environmental applications.
