本文介绍了一种利用高能电子束辐照合成无聚合物PtCu/C纳米粒子的新方法。该方法是一种简单、快速的水溶液一锅法。采用电感耦合等离子体原子发射光谱仪对样品的组成进行了分析。用透射电子显微镜观察了样品的微观结构。在没有使用任何聚合物稳定剂的情况下，在碳载体上沉积了尺寸为2 nm的PtCu纳米颗粒。X-射线衍射分析表明，在未经任何热处理的情况下，形成了无规则的PtCu合金。将辐射合成方法有效地应用于无聚合物PtCu/C的合成中，指出了PtCu系和PtRu系在合金化行为上的差异。
This paper describes a novel synthesis method of polymer-free PtCu/C nanoparticles using irradiation of a high-energy electron beam. The method is a simple and quick one-pot process in aqueous solution system. The compositions were analyzed by inductively coupled plasma-atomic emission spectroscopy. The microstructures of the samples were observed by using transmission electron microscope. PtCu nanoparticles with 2-nm size were deposited on carbon supports without any use of polymer stabilizers. X-ray diffraction analysis showed that the random alloy formations of PtCu were occurred without any heat treatment. Radiolytic synthesis was effectively applied to the synthesis of polymer-free PtCu/C. We pointed out a difference in alloying behaviors between PtCu and PtRu systems which was reported in a previous study.
