- Аннотация: Such carbon nanomaterials (CNMs) as carbon nanotubes (CNTs), carbon nanoflakes (CNFs) and their N-doped derivatives, show sufficient correlations between structure, composition and properties. In this work, the relationships between structure and composition of different types of CNMs as well as enthalpies of their formation were analyzed based on original experimental results and earlier published data. The adiabatic bomb calorimetry technique was used for determination of these values, together with elemental and thermal analysis, electron microscopy, Raman and X-ray photoelectron spectroscopy applied for structure and composition analysis. The contributions of surface (∆fH0298(surf.)) and bulk (∆fH0298(bulk)) components in the values of enthalpies of formation ∆fH0298 for different CNMs were estimated for the first time. It is shown that ∆fH0298(surf.) is highly influenced by the SBET while ∆fH0298(bulk) is defined by the number and homogeneity of inner layers, conformable to graphite structure. In the case of nitrogen-doped CNMs ∆fH0298 is influenced not only by the nitrogen content but by coordination of heteroatom; substitutional nitrogen demonstrate higher effect comparing to pyrrolic and pyridine-like ones.
