我们证明，分步种子介导法可以在非水溶液中扩展(溶剂热合成)，并改进为一种在很大范围内控制钯纳米颗粒(Pd NPs)尺寸均匀的有效方法。在不同的有机胺溶剂中，用甲醛简单还原Pd(Acac)2制得了粒径约为5 nm的单分散Pd纳米粒子。通过改进的分步种子介导法，单分散Pd纳米粒子的尺寸可以精确地控制在大约5到10 nm之间。所制备的Pd纳米粒子无需尺寸选择即可自组装成形状良好的超晶格晶体。
We demonstrated that stepwise seed-mediated growth could be extended in non-aqueous solution (solvothermal synthesis) and improved as an effective method for controlling the uniform size of palladium nanoparticles (Pd NPs) in a wide range. The monodisperse Pd NPs with the size of about 5 nm were synthesized by simply reducing Pd(acac)2with formaldehyde in different organic amine solvents. By an improved stepwise seed-mediated synthesis, the size of the monodisperse Pd NPs can be precisely controlled from approximately 5 to 10 nm. The as-prepared Pd NPs could self assemble to well-shaped superlattice crystal without size selection process.
