以硝酸银和柠檬酸三钠水溶液为原料，甲醛作为还原剂，在微波照射下可快速制备出大尺寸、粒径可控的纳米银。微波辐照制备的银纳米粒子的大小和大小分布与初始反应溶液中银阳离子的状态密切相关。在初始反应溶液中柠檬酸银的形成允许产生具有小尺寸的纳米银。(C) 2003 Elsevier B.V.版权所有
Large-scale and size-controlled silver nanoparticles can be rapidly prepared under microwave irradiation from an aqueous solution of silver nitrate and trisodium citrate in the presence of formaldehyde as a reductant. The size and size distribution of the resulting silver nanoparticles prepared under microwave irradiation are strongly dependent on the states of silver cations in the initial reaction solution. The formation of silver citrate in the initial reaction solution allows for yielding silver nanoparticles with a small size. (C) 2003 Elsevier B.V. All rights reserved.
