Abstract

We synthesized needle-shaped Ag₂CO₃ and triangular plates of Ag by applying ultrasonic irradiation to the solid-liquid system, Ag₂O/H₂O. The samples obtained were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and inductively coupled plasma emission spectrometry (ICPES). The ICPES data confirmed that ultrasonic irradiation increased the solubility of Ag ₂O in distilled water. Applying low-frequency ultrasonic irradiation accelerated the dissolution of Ag₂O and enabled needle-shaped Ag ₂CO₃ and the triangular plate of Ag to be obtained by freeze-drying, while applying high-frequency ultrasonic irradiation almost reduced Ag₂O to Ag. A variety of silver related materials could be synthesized using this water-based ultrasonic process that was environmentally friendly without adding a surfactant.
