Controlled Synthesis of Bimetallic Gold-Silver Nanostars: Atomic Insights and Predictive Formation Model (Small 32/2025)
Bimetallic Nanostars
In article number 2410152, Boaz Pokroy and co-workers describe an environmentally friendly, rapid, and temperature-controlled method for synthesizing bimetallic gold-silver nanostars (GNSs). This process involves the reduction of [AuCl4]− and Ag+ ions by ascorbic acid, which initiates nucleation and anisotropic growth, resulting in a gold-core and silver-shell structure of GNSs. Concurrently, a thin layer of AgCl accumulates on the surface of the GNSs. A comprehensive analytical and theoretical model developed in this study allows for the prediction of optimal synthesis conditions. This model helps in achieving the desired morphology and size of the nanostars and supports the proposed mechanism of their formation.
