Abstract

A fundamental advance in the intercalation chemistry of clays is the formation for the first time of smectite clay heterostructures with regularly stratified organic and inorganic exchange cations, e.g. the fluorohectorite heterostructure with gallery cations Na⊕ and C16H33PBumath image shown in the figure. Their transformation into rectorite-like alumina pillared analogues is also demonstrated.
