摘要
以醋酸钠溶液作为稳定剂,采用液体多元醇方法合成了Pt/C纳米复合材料,并利用X射线衍射(XRD)和透射电子显微镜(TEM)对其进行了表征.结果表明,在合成溶液中加入少量的醋酸钠,合成得到的铂纳米粒子具有细小和均匀的粒径,并高度分散在碳载体上.合成溶液中醋酸钠和铂盐的摩尔比是影响铂纳米粒子的粒径和粒径分布的主要因素.
Pt/C nanocomposites were synthesized by a polyol process adding a small amount of sodium acetate as stabilizer, and characterized by X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The effects of the added amount of acetate solution on the size and size distribution of Pt nanoparticles in Pt/C nanocomosites were discussed. It was found that sodium acetate can be used as a good stabilizer for preparing Pt/C nanocomposites in liquid polyol solution. When a small amount of sodium acetate solution is added into the polyol solution, the Pt nanoparticles become small and uniform, and are highly dispersed on carbon support. The mole ratio of sodium acetate to platinum salt in the polyol solution is the main factor influencing the size and size distribution of Pt nanoparticles in Pt/C nanocomposites.
