The droplet phase of a reverse microemulsion formed by the surfactant cetyltrimethylammonium ferrocyanide was used as a matrix to synthesize nanoparticles of nickel hexacyanoferrate by adding just a solution of NiCl2 to the microemulsion media. Dynamic light scattering and small-angle neutron scattering measurements show that the reverse microemulsion droplets employed have a globular structure, with sizes that depend on water content. Transmission electron microscopy and electron diffraction are used to obtain information about the structure of the synthesized nanoparticles. The results show that the size and shape of the coordination compound nanoparticles correspond with the size and shape of the droplets, suggesting that the presented system constitutes an alternative method of the synthesis of metal hexacyanoferrate nanoparticles.
由表面活性剂十六烷基三甲基铵亚铁氰化物形成的反相微乳液的液滴相被用作基质，通过向微乳液介质中仅加入NiCl₂溶液来合成六氰合铁酸镍纳米颗粒。动态光散射和小角中子散射测量表明，所使用的反相微乳液液滴具有球状结构，其尺寸取决于水含量。透射电子显微镜和电子衍射用于获取有关合成纳米颗粒结构的信息。结果表明，配位化合物纳米颗粒的尺寸和形状与液滴的尺寸和形状相对应，这表明所提出的体系构成了一种合成金属六氰合铁酸纳米颗粒的替代方法。
