摘要

Synthesis of palladium nanoparticles by pulsed electrolysis was investigated in the room-temperatureionic liquid 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) using palladium chloride (PdCl2) asthe palladium source. A palladium-coated carbon (Pd/C) catalytic electrode was synthesized by directdeposition of palladium on a carbon paper working electrode. The size and distribution of thepalladium particles were easily controlled by varying the electrolysis conditions such as theoverpotential, holding time of the applying potential, and temperatures. The composition, crystalstructure, and morphology of the palladium were confirmed by scanning electron microscopycombined with energy dispersive spectroscopy and transmission electron microscopy. The uniformlydistributed palladium nanoparticles had an average size of 3.6 nm with a standard deviation of 0.4.
