微乳体系相行为研究及铂纳米微粒的制备

Studies on the phase of microemulsion system and preparation of platinum nonometer particles

对十六烷基三甲基溴化铵 (CTAB) -正辛醇 -环己烷 -H2 O微乳体系相行为进行了研究。采用分光光度计测量了表观稳定的微乳体系的吸光度的变化 ;然后采用 3种CTAB与正辛醇配比的微乳体系在 30℃下制备出了Pt纳米微粒 ,还原剂为水合肼。经透射电镜分析得出 :溶水量较大的微乳体系可以制备出粒径较小 (d =3nm)

The phase behaviors of microemulsion system of CTAB,cyclohexane,water,were studied and assayed the luminousness of microemulsion system using the spectrophotometer Then platinum nanometer paticles were prepared by the microemulsion system in the temperature of 30℃.By the analysing of TEM,extensive and stable microemulsion system can prepare platinum nanometer paticles ,the paticle diameter is only three nanometer and the distribution is very homogeneous.
