In this paper, we demonstrate the formation of hybrid nanostructures consisting of two distinctive components mainly in a one-to-one ratio. Thermolysis of inorganic nanotubes (INT) and closed-cage, inorganic fullerene-like (IF) nanoparticles decorated with a dense coating of metallic nanoparticles (M = Au, Ag, Pd) results in migration of relatively small NPs or surface-enhanced diffusion of atoms or clusters, generating larger particles (ripening). AuNP growth on the surface of INTs has been captured in real time using in situ electron microscopy measurements. Reaction of the AuNP-decorated INTs with an alkylthiol results in a chemically induced NP fusion process at room temperature. The NPs do not dissociate from the surfaces of the INTs and IFs, but for proximate IFs we observed fusion between AuNPs originating from different IFs.

无机表面上的金属纳米晶体成熟

在本文中，我们演示了由两个不同组分组成的杂化纳米结构的形成，主要是一对一的比例。无机纳米管（INT）和密闭的无机富勒烯状（IF）纳米颗粒的热分解，装饰有金属纳米颗粒（M = Au，Ag，Pd）的致密涂层，导致相对较小的NP迁移或表面增强的Pb扩散。原子或簇，产生更大的粒子（成熟）。使用原位电子显微镜测量实时捕获了INT表面的AuNP生长。AuNP修饰的INT与烷硫醇的反应导致在室温下化学诱导的NP融合过程。NP不会从INT和IF的表面解离，但是对于邻近的IF，我们观察到了源自不同IF的AuNP之间的融合。
