Shape-controlled Pd Nanoparticles in the Mixed Surfactants by Ultrasonic Irradiation
Nano-Pd 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 nano-Pd particles were controllable by adjusting the ratio of CTAB and SDS.The polygonal nano-Pd 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-1 compared to that obtained without surfactant.
