摘要
由于体积效应和表面效应,纳米铁颗粒在电子、环保、生命科学以及机械等行业具有非常广泛的用途。液相法就是在均相溶液中,利用各种途径引发的化学反应,通过均相或异相成核及扩散生长而制备出粒径可控、分布窄的纳米材料。介绍了冷冻干燥法、电化学沉积法、微乳液法等制备纳米铁颗粒的方法以及液相法存在的问题和发展方向。
Nanometer materials were applied to electron ,environment protection,life sciences and mechanism because of their volume effect and surface effect. The preparation of iron nanoparticles were reviewed, including freeze dry method, electrodeposition, weenie latex. Liquid-phase could synthesize nanometer materials with narrow size distributions and functional surfaces, enabling both the formation of order arrays and the controlled tethering of nanometer materials to solid substrates by chemical reaction in homogeneous solution which leads to homogeneous or heterogeneous nucleation and diffusion growth. The recent progress and problem in liquid-phase method were discussed.
