Synthesis and characterization of Pd-poly(N-vinyl-2-pyrrolidone)/KIT-5 nanocomposite as a polymer-inorganic hybrid catalyst for the Suzuki-Miyaura cross-coupling reaction

► Pd-poly(N-vinyl-2-pyrrolidone)/KIT-5 was prepared as a novel nanocomposite. ► Nanocomposite was prepared based on a cage-type mesoporous system. ► Catalyst showed excellent activity for Suzuki-Miyaura reaction in water. ► Stability of the catalyst was excellent and could be reused 8 times.
