Abstract

Layered titanates including transition metal in interlayer space were prepared by ion exchange process. Ammonia adsorption was performed into the transition metal-including layered titanates by aqueous liquid and gas phase. X-ray diffraction patterns of the sample with aqueous liquid and gas phase adsorption confirm that ammonia can be adsorbed without collapse of the titanate layered structure. Further, there was a large increase in the ammonia adsorption amount for the sample with gas phase adsorption comparing to that with the aqueous liquid phase adsorption. Such large amount of ammonia adsorption results from the elimination of the water molecules coordinated with the metal cation between the layers by preheating.
