修饰电极基础问题，请教！急哦！
|
|||
|
我们现在想把碳纳米管修饰到玻碳电极表面上，原文如下：The glassy carbon(GC) electrode (Φ= 4 mm) was polished with 1.0, 0.3 and 0.05um alumina slurry, respectively, and then ultrasonically cleaned in ethanol and water. In 10mL of 0.2 wt% SDS aqueous solution, 10 mg of the acid-treated MWNT was ultrasonically dispersed to give a black suspension of 1.0 mg/mL. Subsequently, 20 ul of this black suspension was cast on a cleaned GC electrode surface. 但没有参考文献，不知道具体的处理方法，尤其是如何将碳纳米管酸处理，有没有哪位师兄师姐做过，请指教一下啊。 [ Last edited by Rainycc on 2009-2-27 at 10:06 ] |

The synthesized MWCNTs were purified by refluxing them with 60% HNO3 at 90 ◦C for 2 h. Then, the mixturewas diluted withwater, filtered, washed with excess de-ionized (DI) water and dried at 50 ◦C in a vacuum oven for overnight. After the purification process, the surface oxidation of the MWCNTs was carried out by refluxingMWCNTsin 4MH2SO4 +4MHNO3 at 90 ◦C for 5 h. Finally, the treated MWCNTs were diluted with water, filtered, washed with excess DI water, and dried at 50 ◦C in a vacuum oven for overnight. 文献中基本上就是硝酸这样去处理的，不过没有做过！ |
