Oil Matrix Technique for Investigation of Competitive Chemisorption and Interactions between Coadsorbed Species on Metallic Films

Abstract

A technique to obtain intense infrared spectra over a wide frequency range for molecules adsorbed on metal particles dispersed in a hydrocarbon medium is described. New applications of this technique to determining extents of adsorption in competitive chemisorption situations and the interactions of coadsorbed species are given. Band shifts are interpreted in terms of electronic factors for ND//3 and NH//3 coadsorbed with PF//3 on Fe, Ni, and Cu; for H//2O with BCl//3 on Ni; for trimethyl phosphite with CO on V, Fe, Ni, and Cu; and for alkylamines with CO on Fe and Ni.
