САЖЕТАК / ABSTRACT:
Montenegro produces a significant amount of grapes annually for both commercial and domestic purposes. Wooden biowaste that is left after grooming poses an environmental issue as it calls for an adequate management plan. This study investigates hydrothermal treatment as an efficient strategy to convert this abundant waste into a high-quality, carbon-based energy storage material. The activation process took place in a hydrothermal reactor with ZnCl2 aqueous suspension under 200°C. The material was further carbonized at 700 °C until lignin, cellulose, and hemicellulose completely decomposed. The structure of the obtained materials was investigated by means of FTIR spectroscopy. The carbonized sample was analyzed as an electrode material for supercapacitors in typical aqueous electrolytes. Cyclic voltammograms were recorded in different pH environments. The results showed that AC reached the maximum specific capacity of 104.3 F g-1 in H2SO4. This implicates thus obtained electrode material to be a promising candidate for use in energy storage systems.
