中文摘要：

采用化学还原方法成功地合成了CuTsPc修饰的纳米Pt胶体，对合成的纳米铂颗粒进行了表征。X射线光电子能谱（XPS）测试表明胶体中的Pt以零价态存在，透射电子显微镜（TEM）照片显示胶体中纳米铂颗粒分散均匀，平均粒径约为3.7nm。选用摩尔比为nPt：nPt=1：10时，利用傅里叶变换红外光谱技术（FTIR）检测到合成的纳米Pt粒子表面原子暴露在修饰离子之外，所修饰的四磺酸基酞菁铜本身又具有催化作用，使得这种粒子在复合催化领域极具应用前景。

英文摘要：

Pt nanoparticles modified by substituted phthalocyanine were synthesized successfully by chemical reduction. The test results of XPS show that Pt particles existe as Pt atoms. The test results of TEM show that the resulting particles were homo-dispersed with supports of copper（ Ⅱ ） phthalocyanine-3,4＇ ,4＇ ＇ ,4＇ ＇ ＇ -tetrasulfonic acid （CuTsPc）, and its diameter is about 3.7 nm. Typical Pt nanoparticles, prepared with nPt：nPt=1 ： 10, were used to analysize the exposed Pt surface. The resultant Pt nanoparticles has active Pt atoms. Furthermore, the modified CuTsPc is a good catalyst itself, made it has potential in catalytic field.
