【讨论】热分解制备Ag纳米粒子
|
|||
|
Yadong Li 在jacs上发表的Ag, Ag2S, and Ag2Se Nanocrystals: Synthesis, Assembly, and Construction of Mesoporous Structures（J. AM. CHEM. SOC. 2008, 130, 4016-4022），介绍了一种很简单的制备Ag纳米粒子的方法。 Briefly, 4.7 nm Ag particles were made by adding AgNO3 (0.5 g) to solvent ODA (10 mL) at 180 °C. The mixture was magnetically stirred for 10 min in air. After reaction, particles were collected at the bottom of the beaker. 大家有谁重复过这个实验？我怎么重复不出来。 文章中提到，Furthermore, the solvent ODA used in our synthesis is testified to be recycled. After the final products were collected at the bottom of the beaker, the residual ODA can be used for the next synthesis. 十八胺可以重复利用，银纳米粒子会沉到底部，可是我的整个体系怎么都是很深的颜色呢 |
