The reaction of C-60/catalyst with hydrogen gas was studied at 400 degrees C and 50 bar of H-2 pressure. The addition of Pt- or Ni-catalysts significantly accelerated kinetics of the hydrogenation reaction and resulted in a dramatic change of the C60Hx crystal structure. Samples reacted without catalyst preserved the fcc structure typical for pristine C-60 but with expanded unit cells. Fulleranes C60Hx obtained using catalytic hydrogenation exhibited not only the fcc structure (at relatively low hydrogenation degree) but also the bcc structure of C60Hx (with x %26gt; 18). The bcc structure corresponds to highly hydrogenated material with an average volume per C-60 molecule of 817-849 angstrom(3).
