Abstract: With cetyltrimethylammonium bromide (CTAB) as a surfactant, a series of palladium nanoparticles with various morphologies were successfully synthesized by controlling the concentrations of CTAB and NaBH4 in an aqueous solution. The morphology of the Pd NPs evolved from nanospheres as interconnected networks with a rise in the CTAB concentration. The CTAB and NaBH4 concentrations were important factors for the control of the final shape of the Pd nanoparticles.

Key words: palladium nanoparticle, morphological evolution, surfactant, reducing agent
