A novel environmentally friendly solution-based method for preparing dispersed silver particles is described. The simple and convenient approach consists in heating silver oxide particles dispersed in a highly alkaline water/acetone mixture. The data presented clearly show that acetone reduces completely and rapidly Ag(2)O particles to metallic silver at 60°C. A mechanism explaining the provenance of the electrons responsible for the reduction of silver is proposed.
一种新颖的环保的基于溶液的方法被用于制备分散的银颗粒。这个简单便捷的方法包括加热分散在高碱性水/丙酮混合物中的氧化银颗粒。所呈现的数据清楚地表明，在 60°C 时丙酮能迅速将 Ag2O 颗粒完全还原成金属银。本文提出了一个解释产生还原银的电子的来源的机制。
