Abstract
Carbon monoxide is associatively adsorbed on silica-supported iron to give four surface complexes, identifiable by distinct infrared bands, two involving linearly bonded CO and two involving bridge bonded CO. The appearance of these species is enhanced by the addition of 0.5%K 2O or 2.5%Al 2O 3 as promoters in the iron. The biggest effect of K 2O is to increase the availability of sites for linear bonding of CO whereas Al 2O 3 has a more general effect possibily due to stabilisation of an enhanced surface area of exposed iron.
