Abstract

Temperature-programmed desorption (TPD) and infrared (IR) spectroscopic studies have been used to identify the nature of adsorbed CO on polycrystalline cobalt surface at room temperature. Linear and bridged molecularly adsorbed CO surface species have been identified by their stretching frequencies at 1990 and 1800 cm-1 Linear-type CO desorbs without dissociation to give desorption peak maximum at 350 K while bridge-type CO dissociates to produce CO2 at the desorption maximum temperature 440 K.
