The object of the research is fullerite.
The aim of the work is to develop the technology of hydrogen saturation of fullerite.
Methods of investigations are the arc method of carbon nanostructure synthesis in the gas phase, scanning and transmission electron microscopy, differential thermal analysis, X-ray phase analysis, spectral photometric analysis.
The deficiency in natural sources of hydro-carbon fuel and global environmental problems have aroused great interest in using hydrogen as a universal synthetic energy carrier for stationary and mobile applications. This approach is conditioned by the unlimited sources of raw materials to produce hydrogen, the high hydrogen energy capacity, the technological flexibility and safety of the energy conversion processes using hydrogen as respects to the environment.
The development of efficient methods for compact hydrogen storage is the key problem of its utilization. The fullerite is a promising material for hydrogen storage.
The work has given the following results:
- the physical absorption of hydrogen with fullerite has been studied;
- it has been shown that C60 fullerite saturation with the lattice hydrogen to the C60H4 formula is possible and under normal condition hydrogen is involuntary desorbed from the lattice;
- the sequence of the hydrogenated fullerene molecule C60H60 formation is as follows: the dissolution of molecular hydrogen in octahedral interstitial sites of the fullerite fcc lattice, the dissociation of hydrogen molecules at their transition to the tetrahedral interstices, the interaction between a hydrogen atom and a fullerene molecule;
- the model of interaction between H2 molecule and C60 fullerite has been suggested;
- the method of rapid analysis of fullerenes in solutions has been developed;
- the topological model of C60 molecule hydrogenation has been suggested;
- the mechanism of evaluating the degree of the C60 molecule hydrogenation has been suggested.
