Metal hydrides formation and hydrogen spillover over Ru/Al2O3 and Ru/AC catalysts
Supported ruthenium nanoparticles are a promising alternative to more noble metals such as Pt or Pd as catalysts for hydrogenation and oxidation reactions. With this experiment we aim to investigate the nature of the Ru-H species formed upon dosing H2 onto highly dispersed Ru catalysts supported on transition alumina and activated carbon supports, as well as the occurrence of hydrogen spillover from the metal surface onto the support. The experiment is part of a collaboration with our industrial partner Chimet S.p.A. The catalysts were already investigated and tested in catalysis in our labs, and Inelastic Neutron Scattering (INS) will provide fundamental insights on the nature of the Ru-H species formed at the metal nanoparticles surface in the presence of H2, as well as on the (possible) occurrence of H-spillover phenomena involving the supports. Previous INS experiments on supported Pt and Pd catalysts (7-05-466, 7-05-514, 7-05-493) demonstrated that this approach is very valuable for better understanding the behavior of this typology of catalysts under hydrogenation conditions, and we are thus confident that fundamental results could be obtained for Ru as well.
