A one-pot strategy for the nucleation, growth, morphogenesis, and passivation of 1.4 nm Au nanoparticles (NPs) on self-assembled rosette nanotubes (RNTs) is described. Tapping-mode atomic force microscopy, transmission electron microscopy, energy-dispersive X-ray analysis, and selected-area electron diffraction were used to establish the structure and organization of this hybrid material. Notably, we found that the Au NPs formed were nearly monodisperse clusters of Au(55) (1.4-1.5 nm) nestled in pockets on the RNT surface.
本文描述了一种在自组装蔷薇状纳米管(RNTs)上实现 1.4nm 金纳米粒子(NPs)成核、生长、形态发生和钝化的一锅法策略。利用原子力显微镜、透射电子显微镜、能谱分析和选区电子衍射对该杂化材料的结构和组织进行了研究。值得注意的是,我们发现形成的 Au NPs 是近单分散的 Au(55)(1.4-1.5nm)簇,嵌在 RNT 表面的口袋中。
