Pillared Clays and Pillared Layered Solids

Abstract: Pillaring is a commonly used procedure to transform a layered crystalline inorganic compound into a material with microporosity and mesoporosity. First, the terms "layered compound, pillaring, pillaring agent and interlayer region" are defined, and then the term pillared layered solid or pillared compound. In the second part, the standard characterization methods and procedures and a systematic classification scheme are proposed.

“…Pillaring (i.e., intercalation) by organic and/or inorganic agents in the interlayer space is a common way to enhance the porosities of clay minerals. According to the IUPAC definition, pillaring is a process by which a layered compound is transformed into a thermally stable micro-and/or mesoporous material that retains the layer structure [1].…”

“…Na química do estado sólido existem muitos compostos chamados de compostos lamelares ou bidimensionais, os quais são formados pelo arranjo de várias camadas ou lamelas [41]. Estas lamelas são formadas por átomos que interagem entre si através de forças covalentes, enquanto que a interação entre átomos de lamelas adjacentes se dá por forças fracas, como por exemplo, forças de van der Waals.…”
