形状控制：在疏水体系中制备了形状均匀的双面、十面、八面、四面体和三角形片状钯纳米晶体，其中油胺（OAm）通过调节晶体应变和表面能之间的平衡，在形状演变中起着至关重要的作用（见图）。所制得的钯纳米晶体对甲酸的氧化具有催化活性。
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.
