The carbon material was prepared by hydrothermal treatment of sucrose and after­wards thermally activated using KOH, NaOH and LiOH. The electro­chem­ical properties of the obtained samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physico­chem­ical properties. All samples showed characteristic capacitor-like beh­aviour. The highest specific capacitance was obtained for the KOH-treated sample, while the increase in capacitance follows the sequence of the growth of ionic radius of a metal from an alkali which is used for activation. It was found that the dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalies of larger radii of metal generated make pores wider and consequently the structure of a porous layer become more accessible to the charge transfer of capacitive response.</p>}, number={7-8}, journal={Journal of the Serbian Chemical Society}, author={Košević, Milica and Krstić, Sanja and Panić, Vladimir and Nikolić, Branislav}, year={2022}, month={Jul.}, pages={867–877} }
