The structural and thermal properties of the hybrid materials, raw andacid activated sepiolite were examined by using Fourier transform infrared, thermalanalysis, X-ray powder diffraction and surface area measurement techniques. Thermalanalysis data prove the remarkable effects of acid activation on the frameworkof sepiolite which are reflected by the intercalation mechanism proceedingthrough the replacement partly of the interstitial water by dimethyl sulfoxidespecies. The protons are directly involved in the actual structure and thusenhances the thermal stability of the complex between dimethyl sulfoxide andthe sepiolite. The noticeable surface area increase of activated sepiolite thanthat of the raw one is connected to the micropore formation. The data presentedin this study may also provide further insight into catalysis studies and theapplication of clays in the growing field of environmental management.eninfo:eu-repo/semantics/openAccessdimethyl sulfoxidesepioliteinterstitial waterArticle117682
