Effects of preadsorption of organic amine on Al-PILCs structures

As a result, the pillar density decreases because a part of the interlayer space is occupied by the amine and during the calcination, the pillaring precursors are converted into rigid aluminum oxide pillars and the organic compounds are removed reflecting an improvement in the orientation of the clay layers. The surface area of this product increase to reach 624 m2 g−1 and the micropore volume becomes three times higher than that prepared without preadsorption of diethylamine.
