ABSTRACT:
Hydrothermally stable intercalated clays having interlayer (gallery) spacings of about 16 to 18 angstroms or more are provided by pillars comprising aluminum and cerium. Other pillaring metal/rare earth combinations and differing preparation conditions, such as pH, result in different interlayer spacings. Interlayer spacings of 16 to 40 or 18 to 50 angstroms may be produced.
