Palladium nanoparticles protected by polyvinylpyrrolidone (PVP) have been synthesized by the reduction-by-solvent method and deposited onto different supports by impregnation. The catalytic activity of the nanoparticles has been tested in the preferential oxidation of CO reaction. The aging time of...
