| Abstract: | Ultrafine palladium particles immobilized on submicrometer copolymer microspheres were prepared by reduction of palladium ions in the presence of the copolymer microspheres. Copolymer microspheres with surface carboxylic or cyano functionality were used. Transmission electron microscopy observation and X-ray diffraction analysis indicated that ultrafine palladium particles of nanometer size were formed and were attached on the surface of the copolymer microspheres. The interaction between palladium particles and surface functionality of the copolymer microspheres was studied by IR spectroscopy and X-ray photoelectron spectroscopy.
