| Outline of Final Research Achievements |
Steps play key roles in catalytic reactions on nano-particle catalysts, but the effects of the alignment of gas-phase molecules on the adsorption processes on stepped surfaces is not understood well. In the present study, by scanning a narrow spin-rotational state-selected O2 beam across a curved Pt(111) surface on which step density varies linearly with the horizontal distance from the apex of the crystal, we have investigated the alignment-dependent O2 adsorption and CO oxidation on stepped Pt surface. We also prepared a hyperpolarized ortho-H2 beam using the magnetic deflection technique and developed a system that allows us to investigate how the nuclear spin of H2 affects its adsorption and desorption processes.
