- We have successfully synthesized ionic liquid (IL)-stabilized palladium (Pd) nanoparticles (NPs)
by electrochemical reduction. The particle size was controlled by adjusting the current density.
Transmission electron microscopic (TEM) images showed that the average diameters of the Pd
NPs were 2.4, 3.2, and 3.5 nm, depending on the synthetic conditions. Particle size increased as
the current density and the length of the alkyl chain in the cation decreased. X-ray diffraction of
the resulting NPs indicated that the particles had a crystalline structure. Overall, the results show
that NPs can be finely tuned according to the kinds of ILs employed, as well as by electrochemical
