摘要：

A thin film made of an ion-exchangeable layered compound, K4Nb6O17, was prepared by a novel method. Fine particles of K4Nb6O17 obtained by wet-grinding of the powder were coated on a substrate and calcined. Recrystallization of the fine particles at 1073 K was confirmed by XRD and SEM, and very flat and large crystals with the b-axis perpendicular to the substrate surface were obtained. The obtained thin film had a layered structure and an ion-exchange property similar to that of K4Nb6O17 powder. The adsorption of CO was investigated for the thin film calcined at 1073 K by IR spectroscopy. The initially IR-inactive H+ species were suggested to be transformed into OH groups as a result of CO adsorption at the interlayer space. (C) 1998 Elsevier Science Limited. All rights reserved.
