The all-carbon electrodes are synthesized via the plasma reformation of natural fats and functionalized by microwave-assisted doping using leaf extracts from a variety of horticultural plants such as bok choy, chrysanthemum, and spinach. The resulting nanostructures possess a high loading of electrochemically active dopants and a desirable morphology for energy storage. This combination enables the electrodes to exhibit excellent supercapacitor performance.
