A simple route to water-soluble size-tunable monodispersed Pd nanoparticles from light decomposition of Pd(PPh3)4

Water-soluble monodispersed palladium nanoparticles of diameters 2.5, 5 and 10 nm controlled by varying the concentration of CTAB micelles have been prepared from light decomposition of Pd(PPh3)4.
