Effect of Water on CO Adsorption on CaNaY Zeolite: Formation of Ca(HO)(CO), Ca(HO)(CO) and Ca(HO)(CO) Complexes.

Efficient CO capture materials must possess a high adsorption capacity, suitable CO adsorption enthalpy and resistance to water vapor. We have recently reported that Ca cations exchanged in FAU zeolite can attach up to three CO molecules. Here we report the effect of water on the adsorption of CO.
