Shape control : Uniform Pd nanocrystals in the shape of icosa‐, deca‐, octa‐, tetrahedron, and triangular plate were prepared in a hydrophobic system in which oleylamine (OAm) plays a crucial role in shape evolution by mediating the counterbalance between crystal strain and surface energy (see picture). The as‐obtained Pd nanocrystals are catalytically active in the oxidation of formic acid.
