Ferrite magnetic nanoparticles Fe3O4 (2 g) and NiCl2·6H2O (10 wt% of nickel on ferrite) were stirred at room temperature in aqueous solution for 1 h. After impregnation, the suspension was adjusted to pH 12 by adding sodium hydroxide (0.5m) and stirred for 10 to 12 h. The solid was washed by distilled water (5 10 mL). The obtained metal precursors were reduced by adding an aqueous solution of 0.2m NaBH4 dropwise under gentle stirring in an ice– water bath for 30 min until no bubbles were observed in the solution. The resulting Fe3O4Ni MNPs were ultrasonicated for 10 min and then washed with distilled water and subsequently with ethanol. The synthesized Fe3O4Ni MNPs were characterized by several techniques such as XRD, ICP-AES, TEM, and FEG-SEM-EDS.,請問這里面的硼氫化鈉應該怎么處理?我直接配制的硼氫化鈉溶液加到溶液中去,沒有得到理想效果。 [ Last edited by liwentao2010 on 2015-3-18 at 18:37 ] |
