Enhanced Control of Single Crystalline Ag Dendritic Growth on Al Foil via Galvanic Displacement and Simultaneous Oxidation of D‐Glucose

Small Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 28, 2025

A facile synthesis platform for the formation of stable single crystalline Ag dendrites is demonstrated. Using a porous electrospun polyacrylonitrile nanofiber network on Al foil as template facilitates more uniform dendritic growth in presence D‐glucose. In contrast, denser polymer restricts nucleation site availability foil, highlighting critical role substrate. The silver reduced solution when two simultaneous processes occur: electroreduction + D‐glucose and galvanic displacement driven by interaction with aluminum High‐resolution transmission electron microscopy analysis shows nature grown from substrate, revealing atomic structures closely packed layers forming highly faulted face‐centered cubic hexagonal close‐packed structures. remarkable long‐term stability primarily attributed to their structure, additional contributions capping D‐gluconic acid, confirmed Raman analysis. This novel approach generation has significant potential applications such surface‐enhanced scattering, which date been considered be very sensitive environmental effects.
