摘要：
A natural saponite was intercalated and pillared with hydroxy-aluminium-chromium oligomers. The ntercalation solutions were characterized by visible spectroscopy and the pillared saponites mainly by chemical analyses, X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS) and nitrogen adsorption. The catalytic behaviour of these materials in the dehydrogenation of ethylbenzene was investigated. The selectivity to styrene was found to increase as the chromium content of the pillared clays decreased.
