摘要：

Metal-support interactions were investigated by H-2 NMR for deuterium adsorbed on Rh supported on SiO2, Al2O3, TiO2 (in a non-SMSI state), NaY zeolite, and MgO. Two types of adsorbed species, Dm and Dw, with distinct chemical shifts irrespective of supports, were detected on all supports except that Dw was not detected on Rh/Al2O3. The molar fractions also support dependent. These results indicate that the major effects of the support are the number of active sites and the motions of Dm and Dw.
