A thermoresponsive and recyclable nanomaterial was synthesized by surface modification of magnetite nanoparticles (MNPs) with poly(N-isopropyla-crylamide-co-diethylaminoethyl methacrylate) (P(NIPAAm-co-DEAEMA)), having PNIPAAm as a thermoresponsive moiety and PDEAEMA for catalyst binding. Palladium (Pd) nanoparticles were incorporated into this material, and the resulting nanocatalyst was efficient in the hydrogenation of olefins and nitro compounds with turnover frequencies (TOFs) up to 750 h-1. Consistent catalytic activity in 10 consecutive runs was observed when performing the hydrogenation at 45 degrees C, i.e., above the lower critical solution temperature (LCST) of the copolymer (37 degrees C), followed by cooling to 15 degrees C, i.e., below the LCST of the copolymer.
