乙醇可以還原氯金酸生成納米金嗎? 已有10人參與

看到一篇文獻說是用乙醇還原氯金酸,在四氧化三鐵納米粒子存在的情況下可以制備得到核殼型的納米材料,對于乙醇能夠還原我了解的比較少,也沒查到資料,請問各位,乙醇是能夠還原氯金酸嗎? 文獻原話: The coating experiment was done by reduction of HAuCl4 in an ethanol solution [2]. Approximately 4 mg magnetite nanoparticles suspended in ethanol (1 ml) with 2 ml of HAuCl4 aqueous solution. Schematic reaction is shown in Fig. 1a. The sample was stirred in a sonication bath from time to time for 2 h at room temperature. The resulting mixture turned dark red during sonication. After that time solution was allowed to stand unmixed form about 15 min, then the prepared magnetite–gold nanocomposites were separated from the colloid by a permanent magnet. Resulting nanoparticles were washed three times with distilled water for use in further experiments. B. Kalska-Szostko et al. / Applied Surface Science 258 (2012) 2783– 2787 他提到的參考文獻好像也并不是完全一樣的做法。這是參考文獻2的信息: Hindawi Publishing Corporation Journal of Nanomaterials Volume 2009, Article ID 962021, 5 pages doi:10.1155/2009/962021 |
