采用γ射线辐射法成功制备了铂-钯-碳纳米管(Pt-Pd/CNTs)纳米复合材料。分别介绍了辐照剂量、溶液pH值和表面活性剂对Pt、Pd的还原率
Pt-Pd沉积在CNTs上的分布及其粒径大小的影响。扫描电镜(SEM)和元素能谱分析(EDS)测试结果表明:纳米合金粒子Pt-Pd(平均粒径10nm左右)均匀地分布在CNTs表面;辐照剂量的增加、调整溶液pH值至弱碱性、添加表面活性剂均可以使Pt和Pd的利用率有明显的提高。
Pt nanoparticles supported on carbon nanotubes (CNTs) were obtained by γ -ray irradiation and characterized by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results indicated that characteristics of the Pt-Pd nanoparticles were affected by radiation dose
pH value and surfactant. The Pt-Pd nanoparticles
about 10 nm in diameter
were uniform in both shape and size and well dispersed on the carbon nanotubes. The efficiency in using the Pt and Pd could be improved by increasing the dose
adjusting pH value of the solution to the range of 7 to 8.5
or adding surfactant.
