In the past decade there has been a renewed interest in the use of clay minerals as catalysts and catalyst supports. In general, clays break down into two broad groups: cationic clays, which nature prefers, and anionic clays. Anionic clays, which are the topic of our study, are rare in nature but relatively simple and inexpensive to prepare in the laboratory. Naturally occurring hydrotalcite, Mg6Al2(OH)16CO3•4H2O, is an example of an anionic clay.1
