Investigation of the surface of Ni-Pd catalysts by IR spectroscopy

  • 36 Accesses


The reaction of carbon monoxide with the surface of Ni, Pd, and Ni-Pd catalysts, deposited on γ-Al2O3, was investigated at 25°C by IR spectroscopy in conjunction with an adsorption volumetric technique. The IR spectra contained the following absorption bands (v, cm−1): 2020–2100 (AB1) (linear and subcarbonyl forms of adsorbed CO); 1945–1985 (AB2) (bridging); 1920–1940 (AB3) with a shoulder at 1870–1885 (AB4) (bridging and many-center). In the spectrum of Ni the absorption band AB5 appears at 1770–1780 (CO-Ni+). It appears with surface coverage a ≥ 1.3 mole CO/mole εM. The optical density (A) of AB1 for Ni97Pd3 is appreciably higher than for the other investigated samples. In the Ni-Pd catalysts the intensity of AB2 in relation to AB1 is higher than in nickel. The introduction of K+ ions into the support of the bimetallic sample reduces the optical density of AB1. In modified Ni-Pd-K the AB3 and AB4 bands disappear.
