ИСТИНА

The continuous growth of the number of investigations of different types of CNMs is linked to the perspectives of their use in electronics and energy storage, catalytic industry as well as adsorbents. Numerous of works are devoted to their synthesis and investigation of physico-chemical properties, studying of correlations between characteristics, theoretical calculations and experimental search for material with the optimal parameters for certain area. Nevertheless, only small part of research is devoted to the key parameters for all types of CNMs - their thermodynamic characteristics. To the best of our knowledge enthalpy of formation, entropy and free Gibb’s energy are determined only for limited number of CNMs. Since carbon nanostructures do not possess the molecular composition as it is common for the classic substances, the question of the calculation of these characteristics till now remains open.
