| Summary: | Polymer-protected, colloidal palladium and platinum nanoparticles were prepared by in-situ reductions from various precursors and investigated as novel catalytically-active systems that could be tailored for special applications. The size, size distribution, and morphology of the metal particles were determined by transmission electron microscopy. Their catalytic activity was tested by the hydrogenation of cyclohexene as a model reaction. Several gold colloids were prepared as well, and characterized by transmission electron microscopy and UV-VIS spectroscopy. Results have been obtained for stable metal colloids protected by various water-soluble polymers and random copolymers, cationic polyelectrolytes, amphiphilic block copolymers, and for metal nanoparticles immobilized on the surfaces of latexes. |
