The state and behavior of hydrogen on ruthenium catalysts

  • 26 Accesses

Conclusions

  1. 1.

    Using adsorption, thermal desorption, and isotopic methods the authors have investigated the state of hydrogen present on the surface of Ru/Al2O3, Ru/SiO2, and Ru black catalysts.

  2. 2.

    Hydrogen can be adsorbed very strongly on the surface of Ru catalysts, and removed only at elevated temperatures. The amount of strongly adsorbed hydrogen sharply increases in going from Ru black to deposited catalysts.

  3. 3.

    Hydrogen adsorbed on Ru can spread over the carrier surface and take part in exchange with the carrier OH groups.
