Authors: RANKIN J. L. , BARTHOLOMEW C. H.
Published: May 2016

The results of adsorption measurements, Möß‐ bauer spectroscopy and XRD provide evidenee for significant changes in the kinetics and stoichiometries of CO, CO2, and H2 adsorptions on Fe/SiO2 and for changes in the bulk and surface chemistry of iron due to addition of K. While decreases in CO and H2 adsorptions, as well as increases in CO2 adsorption and CO dissociation rate are the same as reported earlier for single crystal and polycrystalline iron surfaces, an observed decrease in the extent of reduction to metallic Fe with increasing Kcontent is a new significant result.
