Promoted adsorption of pyridine on nickel

Abstract

Ultraviolet and infrared spectroscopy were used to investigate the adsorption of pyridine on oil-covered nickel films and to study the effects of coadsorbed catalyst poisons. No chemisorption of pyridine was detected on unpoisoned films, but on films previously exposed to oxygen, carbon monoxide, or carbon disulfide, pyridine was coordinately adsorbed. A model for poisoning of metal surfaces by promoted or induced irreversible adsorption of the reactants is presented.
