Palladium nanoparticles (PdNPs) were successfully prepared using xylan-type hemicellulose (XH) as a support and used for the first time as an efficient and recyclable catalytic system in organic synthesis. The morphology, composition, and thermal stability of the catalyst were studied by means of TEM, XPS, XRD, FT-IR, and TGA. The as-prepared catalyst was further catalytically tested in various C-C crosscoupling reactions and exhibited excellent catalytic activity in the Suzuki, Heck, and Sonogashira coupling reactions. The catalyst could be easily recovered by simple filtration and reused at least six times without significant loss of its catalytic activity. This work demonstrates the possibility of using XH as an efficient support for catalysis.
