有做過納米MnO和Mn3O4的沒?求助。。?粗墨I(xiàn)的步驟怎么做不出來。急急。。。。

7.92 g of manganese chloride tetrahydrate (MnCl2•4H2O, 40 mmol, Aldrich Chemical Co., 98 %) and 24.36 g of sodium oleate (80 mmol, TCI Co., 95 %) were added to a mixture composed of 30 ml of ethanol, 40 ml of distilled water, and 70 ml of n-hexane. The resulting mixture solution was heated to 70 °C and maintained overnight at this temperature. The solution was then transferred to a separatory funnel and the upper organic layer containing the Mn-oleate complex was washed several times using distilled water. The evaporation of the hexane solvent produced a pink coloured Mn-oleate powder. 然后再熱分解就可以得到MnO納米顆粒。我根據(jù)文獻(xiàn)的步驟做了,怎么做不出來啊。。求個(gè)人指點(diǎn)。。。。各種感謝。 |
