Ultrasound‐Enhanced Electrosynthesis of Dendritic Silver Nanostructures

ABSTRACT Dendritic silver nanostructures (DSNs) have attracted significant interest due to their unique hierarchical architecture. This work presents a facile ultrasonic‐assisted electrodeposition method for DSNs synthesis using tartaric acid as a morphology‐directing agent. Systematic investigations reveal that ultrasonic irradiation simultaneously refines silver crystallite size and enhances current efficiency from 36.89% to 97.27%. The dendritic morphology is controlled through tartaric acid's facet‐specific adsorption, while Ag⁺ concentration, current density, and temperature collectively regulate the nucleation‐growth kinetics. Under optimized conditions, this method produces uniform DSNs through a simple and scalable process, demonstrating significant potential for high‐quality dendritic silver powder production.
