Using Pd nanoplates as the seeds, Pd‐Cu nanocrystals with planar defects are synthesized. The Cu atoms nucleate from one of the two basal faces on the Pd nanoplates in an asymmetric pattern due to the large lattice mismatch between the two metals. The planar defects are transferred into the Cu lattice. With the use of hexadecylamine and Cl⁻ as the capping agents for Cu{100}, the final Cu‐Pd nanocrystals take a cubic shape in the case of hexagonal seeds with an even number of planar defects, whereas triangular seeds with a single planar defect leads to the formation of right bipyramids.

使用Pd纳米板作为种子，可以合成具有平面缺陷的Pd-Cu纳米晶体。由于两种金属之间的大晶格失配，Cu原子以不对称图案从Pd纳米板上的两个基面之一成核。平面缺陷转移到铜晶格中。与使用十六烷基胺和Cl ^-作为封端剂对Cu {100}，最终的铜-钯纳米晶体采取在具有偶数个面缺陷的六方晶系种子的情况下的立方体形状，而用单个平面缺陷三角形种子导致右双锥的形成。可以在Younan Xia等人的“全文”中找到更多信息。就在第3页386 2020（DOI：10.1002 / cnma.201900653）。
