Abstract

Montmorillonite was pillared with Al2O3-NiO mixed oxide by ion-exchange combined with titration process; the interlayer Na ions of montmorillonite were first exchanged with aluminum hydroxide polycations, and then nickel hydroxide was precipitated between the layers by a titration method. The aluminum hydroxide pillars reacted with the nickel hydroxide at room temperature, and the microporous structure was much stabilized against heating. The specific surface area as high as 300 m2/g was maintained up to 700°C.
