Diffusion-controlled bridging of the Au Island and Au core in Au@Rh(OH)₃ core-shell structure.

ABSTRACT: Hybrid nanostructures have garnered considerable interest because of their fascinating properties owing to the hybridization of materials and their structural varieties. In this study, we report the synthesis of [Au@Rh(OH)₃]-Au island heterostructures using a seed-mediated sequential growth method. Through the thiol ligand-mediated interfacial energy, Au@Rh(OH)₃ core-shell structures with varying shell thicknesses were successfully obtained. On these Au@Rh(OH)₃ core-shell seeds, by modulating the diffusion of HAuCl₄ in the porous Rh(OH)₃ shell, site-specific growth of Au islands on the inner Au core or on the surface of the outer Rh(OH)₃ shell was successfully achieved. Consequently, two types of distinct structures, the Au
