Preparation:Water was used as the solvent in all reactions.For a typical preparation, the silver nanoparticles were prepared by adding 14 g of PVP to 500 mL of silver metal salt (AgNO3,5.6 mM) solution. The solution was then heated at 60 °C in an oil bath for 10 min, and then 37 mmol of NaBH4 was added.The mixture was then allowed to react for another 20 min in an oil bath. The reaction mixture was stirred for 30 min to remove the excess reducing agent (NaBH4). 文中給的加入37mmol硼氫化鈉不知道具體指什么,怎么個加入法,高手幫忙研究研究吧~~ |
