Activated carbon fibers an promising materials for the adsorption-catalytic removal of different undesirable impurities, e.g., hydrogen sulfide from hydrogen. The possibility of increasing the effectiveness of these materials by vacuum deposition of metal coatings (Mo,W,Ni,Ti,Cu) is studied. Magnetron sputtering and electron-beam evaporation techniques are used. Protective titanium carbide coatings, with different carbon content, are obtained by reactive magnetron sputtering. Such coatings improve the resistance to hydrogen and increase chemo- and thermostability without changing catalytic and sorption properties, which is important for catalytic purification.
