T-10 Tokamak Hydrocarbon Films as Storage of Hydrogen and Hydrocarbon Isotopes

The results of the study of the properties and structural features of amorphous hydrocarbon films CDx (x ~ 0.5) obtained in the plasma discharge of the T-10 tokamak are presented, which characterize these films as a hydrocarbon system with carbon sp3 + sp2 states (mainly with sp3 states). The films form a branched three-dimensional fractal carbon network with a fractal structure and a high specific surface. Such a CDx system facilitates accumulation and storage of both hydrogen isotopes and hydrocarbons in a stable state. Its desorption characteristics can be improved by the catalytic effect of iron impurities.
