Bentonite is a type of clay with the most attention, due to the ability to swell, has a interlayer space or have larger pores and flexible structure than the natural zeolite pore so it can be engineered to form bentonite pillared with micropore size and/or mesopores which can be used as selective catalysts, separation agents, supporting materials, adsorbents [2].
