摘要：
Rectangular palladium nanoparticles have been synthesized by the reduction of PdCl2 with ethylene glycol (EG) in presence of cetyltrimethylammonium bromide (CTAB) and disodiumtartarate in acid media. Here CTAB and disodium tartarate acts as surfactant and directing agent for selective yield of nanocubes and nanobars. The morphology of Pd nanocrystals can be tuned by varying concentration of EG, CTAB, and disodium tartarate. The powders were characterized by XRD, FESEM, and TEM studies. Reaction intermediate was studied by UV-Vis spectra and characterized by TG-DTA analysis. An equilibrium mechanism is proposed where Na+ plays an important role in the formation of Pd nanopowder.
