We have investigated the infrared spectra for CO adsorbed on silica supported nickel(Ni-Si), silica supported copper(Cu-Si), silica supported nickel-copper alloys(Ni/Cu-Si) of several compositions with varying CO pressures(0.2 50 torr) at room temperature and on pumping to vacumn at room temperature within the frequency range of 1500 . Four bands(2059.6 2036.5 1868.7 1697.1 ) were observed for Ni-Si, two bands(2115.5 1743.0 ) were observed for Cu-Si and five bands(, 2059.6 2036.4 1899.5 1697.1 ) were observed for Ni/Cu-Si. These absorption bands correspond with those of the previous reports approximately. The bands below 1800 were only observed with Ni metal or Ni/Cu alloy crystal plane containing step at room temperature and the bands observed with Ni-Si and Ni/Cu-Si may be ascribed to CO molecule adsorbed on the adsorption sites near step. The bands below 2000 were rarely observed with Cu metal crystal plane at room temperature and the 1743.0 bands may be ascribed to CO molecule adsorbed on the adsorption sites near step. The band shifts of adsorbed CO with varing Cu contents from 0 to 0.5 mole fraction at the same CO pressure or at the same pumping time to vacumn were below 21 . and comparatively small than those with other ⅠB metal addition. It may means ligand effect of Cu d electron is small.
