Poly(N-isopropylacrylamide)-halloysite (PNIPAM-HNT) nanocomposites exhibited inverse temperature solubility with a lower critical solution temperature (LCST) in water. Palladium (Pd) nanoparticles were anchored on PNIPAM-HNT nanocomposites with various amounts of HNT from 5 to 30wt%. These Pd catalysts exhibited excellent reactivities for Suzuki-Miyaura coupling reactions at 50-70 degrees C in water. In particular, Pd anchored PNIPAM/HNT (95:5 w/w ratio) nanocomposites showed excellent recyclability up to 10 times in 96% average yield by simple filtration.
