A bentonite/PS-SO3H nanocomposite was prepared and used as an acid catalyst for the Biginelli reaction under solvent-free conditions. This acid catalyst was characterized by XRD, SEM, TG, BET and FT-IR. The catalyst showed high thermal stability, good reusability and was environmentally benign. (C) 2011 Published by Elsevier B.V.
