Palladium nanocrystals bound by {110} or {100} facets: from one pot synthesis to electrochemistry.

A facile one-pot tactic is developed for the selective synthesis of either rhombic dodecahedral or cubic Pd nanocrystals with high yields. By applying a mild cleaning process, we establish for the first time reasonable and distinct electrochemical features corresponding to {110} or {100} facet predominated Pd nanocrystals.
