Spectroscopic and catalytic investigations of transition metal complexes intercalated in layered silicates
… catalyzed by copper complexes intercalated into smectite clay minerals show that this type of reaction can be made very selective, due to the environment of the interlamellar layer of the clay mineral. The oxidation of 2,6-dimethylphenol leads to a greater selectivity toward the diphenoquinone …

Sorption mechanisms of dibenzo-p-dioxin/furan from water by smectite clays and theoretical studies on formation pathways of chlorodibenzo-p-dioxins from precursor chlorophenols on smectite clays
Clay minerals may be an important sorptive phase for dioxins in soils, and dioxins are often found in natural clay deposits. Sorption experiments demonstrated that smectites, especially Cs-saponite, effectively adsorbed dibenzo-p-dioxin /furan from water. Adsorption was promoted by exchangeable …

Steric Effects of Alkyl Ammonium Salts on the Combustion of Exchanged Smectite Clays
… the cation exchange capacity (CEC) of clays. Smectite clays were modified with several alkyl ammonium salts varying in number of carbons and the spatial orientation of the carbons about the central nitrogen atom. The clays used, standards purchased from the Source Clay Repository, have …
