Palladium nanoparticles synthesis with controlled morphology obtained by polyol method

The paper deals with the synthesis of Pd nanoparticles with controlled morphology by polyol method at 140 °C, using different palladium precursors (PdCl2 and K2PdCl4) and stabilizers (polyvinylpyrrolidone, PVP, and cetyl trimethyl ammonium bromide, CTAB). Pd nanoparticles synthesized from PdCl2 in the presence of PVP by reduction reaction with ethylene glycol in argon atmosphere have spherical shape and 7.5 nm average size. By using a mixture of surfactants, PVP and CTAB, Pd nanoparticles resulted in polyhedral shapes with the average size of 8.4 nm (for those obtained in air), and 6.3 nm (for those synthesized in argon atmosphere), respectively.
