Recent developments in the intercalation of anionic clays by robust polyoxometal oligomers stem from their potential use as catalytic materials. Many of the anionic clays are strong bases. In the literature, a polyoxometalate of transition metals, such as molybdenum, tungsten, or vanadium, was usually the subject to introduce into the interlayer space of anionic clays. However, the composition of these polyoxometalates is pH dependent, and these oligomers become unstable in a basic environment. In the present work, the oligomers of tetraborate were introduced into the layers of a magnesium aluminum hydroxide hydrotalcite-like compound. Because the tetraborate ions were formed in a basic solution, pillared hydrotalcite-like material of good crystallinity was obtained. The metal hydroxide layer structure was found to remain intact up to 823 K. A systematic study on the preparation and structural characterization of borate pillaring hydrotalcite was carried out. The catalytic behavior of these materials on 2-butanol decomposition was also examined.
