The preferential deposition of Ag on the {111}
facets could be attributed to [Bmim]Cl that selectively binds to
the {100} facets and thus retard their growth along h100i directions.
In previous reports, the synthesis of metal nanocrystals in
the presence of a proper capping agent could lead to the formation
of a wide range of shapes deviated from the thermodynamically
favored forms [22–24].
