A new seed-mediated synthesis of AuHNPs in high yield is described using hydroquinone as a weak reductant and poly(vinylpyrrolidone) as a shape-directing additive. We obtain distinct and small edge lengths of AuHNPs with long-term shape stability. Also, PVP enhances the monodispersity and enables the higher stability of functionalized nanoprisms.
一种新的基于种子的 AuHNPs 高产合成方法被描述，该方法使用对苯二酚作为弱还原剂，聚乙烯吡咯烷酮作为形状导向添加剂。我们得到了具有长期形状稳定性的独特且小的边缘长度的 AuHNPs。此外，PVP 提高了单分散性，并使功能化的纳米棱柱体具有更高的稳定性。
