液相法制备金属纳米粒子

Solution-phase synthesis of metal nanoparticles

  • 摘要: 液相法是在均相溶液中,利用各种途径引发化学反应,通过均相或异相成核及随后的扩散生长而制备出粒径分布窄且表面功能化的纳米尺度材料.介绍了液-液两相法、反相胶束、高温液相法等制备单分散金属纳米粒子的方法和高温液相法制备金属纳米粒子的影响因素,以及近年来在金属纳米粒子的制备和性能研究上的进展,尤其是Co等多种磁性纳米粒子的制备、磁性研究.

     

    Abstract: Solution-phase synthesis can synthesize nanometer-sized materials with narrow size distributions and functional surfaces, enabling both the formation of order arrays and the controlled tethering of nanometer-sized materials to solid substrates by chemical reaction in homogeneous solution which leads to homogeneous or heterogeneous nucleation and diffusion growth. The two-phase reduction method, reverse micelle method, and high-temperature solution-phase synthesis are described as well as the influence factor of high-temperature solution-phase in the preparation of monodisperse metal nanoparticles. Recent progress in the synthesis of metal nanoparticles, especially magnetic nanoparticles, and potential applications are discussed.
