| Popis: |
nanoPd nanoparticles were prepared using ultrasonic irradiation in the PdCl2/H2O/EtOH solution by the addition of a quantity of hexadecyl trimethyl ammonium bromide (CTAB) and sodium dodecyl sulfonate (SDS) . The products were characterized by XRD、TEM and low temperature nitrogen adsorption-desorption. The effects of the composition of CTAB and SDS on the growth morphology of palladium nanoparticles were investigated. The results indicate that the size and morphology of the nanoPd particles were controllable by adjusting the ratio of CTAB and SDS. The polygonal nanoPd particles with a distributed size of 10-20 nm were obtained when the molar ratio of CTAB:SDS was 1:1 and the reaction time was 60min. The nanoparticles obtained by addition of two surfactants (CTAB and SDS) increased the BET surface area by 14 m2∙g-1compared to that obtained without surfactant. |
