请教一下:王志江教授的金
铁合金纳米粒子的合成中,这个合成是油胺油酸需要同时加吗?然后我简单换算了下,油酸油胺大概就一两滴,如果把
醋酸金换成
氯金酸可以吗? 该反应可以在磁力搅拌下进行吗?谢谢
Au-Fe nanoalloys were synthesized by the one-pot wet chemical approach. In a typical experiment, Fe(acac)3 (12.5 mM), Au(OOCCH3)3 (37.5 mM) and the reduction agent of 1,2- hexadecanediol (250 mM) were dissolved in 10 ml octyl ether solution with oleic acid (25 mM) and oleyl amine (25 mM). Under vigorous stirring and Ar atmosphere, the reaction mixture was first heated to 80 ºC and homogenized at that temperature for 1 h, then rapidly raised to 280 ºC and refluxed for 1 h to complete the reaction. Subsequently, ethanol was added into the reacted mixture to precipitate the formed nanoparticles (NPs) after cooling down to room temperature. The resulting dark-red product was separated from the supernatant by centrifugation and washed with mixed ethanol/hexane solvents (1:2) twice and redispersed in hexane.
