In this study, a mixture of activated carbon (AC) and graphene (G) was coated onto the stainless steel (SS) mesh to produce an electrode for the electrochemical capacitor (EC). Different materials, such as carbon nanotube (CNT) mixed with G, were also used in this experiment to compare the electrochemical properties of both electrodes. The electrochemical properties of the electrode were determined by using cyclic voltammetry (CV). The CV curves of the AC/G electrodes showed good capacitive behaviour, and the highest capacitance values obtained for AC/G and CNT/G electrodes in 1M H2SO4 at 1 mVs-1 were 13 Fg-1 and 4.34 Fg-1, respectively. Meanwhile, the highest capacitance values obtained in 6M KOH at 1 mVs-1 were 14 Fg-1 and 12.07 Fg-1 for AC/G and CNT/G electrodes, respectively.

The dates about effect of temperature of carbonizats obtaining from pine bark on evolution of a porous structure and sorption properties of the activated carbons, synthesized by the method of thermoalkaline activation in the presence of КОН were presented. It was determined, that for preparation of activated carbons with the greatest specific surface (1421 and 1655 m2/g) and micropores volume (0.58 и 0.71 sm3/g) pine bark carbonizats reasonable to obtain at temperature 300 and 400 °С correspondingly. The correlation of a iodine sorption with volume of micropores width 0.73–3.0 nm (R2=0.964) and a methylene blue sorption with volume of micropores width 0.84–2.0 nm (R2=0.995), which present in the activated carbons structure, was established. It was shown, that low capacity of the activated carbons to vitamin B12 sorption determine by low mesopores volume with width ≥5 nm (no more than 0.0014 sm3/g). It was shown, that the activated carbon based on carbonizat obtained at 400 °С demonstrates a maximal sorption capacity to a iodine and a methylene blue (1.57 g/g и 697.1 mg/g correspondingly), that in 1.4 and 2.7 times exceeds the dates of an industrial activated carbon for medical purposes.
