Regulating the nanostructure of composite nanoparticles is essential for making them suitable for various applications. In general, the chemical reduction method is employed for preparing metal nanoparticles in the liquid phase. However, complicated techniques are required to control the nanostructure during particle synthesis. The evaporation/condensation method is used for synthesizing nanoparticles in the vapor-phase. Although this method produces impurity-free particles without aggregation, very few studies have been carried out on the synthesis of composite particles in the vapor-phase. In this study, we synthesized composite nanoparticles in the vapor-phase by using the evaporation/condensation method. The results showed that bimetallic nanoparticles are produced by this method. Moreover, it was indicated that the nanostructure of the synthesized nanoparticles is influenced by the order of the electric furnace with different temperatures.
调控复合纳米粒子的纳米结构对于使其适用于各种应用至关重要。一般来说，化学还原法用于在液相中制备金属纳米粒子。然而，在粒子合成过程中需要复杂的技术来控制纳米结构。蒸发/冷凝法用于在气相中合成纳米粒子。尽管这种方法能产生无杂质且无团聚的粒子，但关于气相中复合粒子合成的研究却很少。在本研究中，我们通过蒸发/冷凝法在气相中合成了复合纳米粒子。结果表明，这种方法能制备出双金属纳米粒子。此外，还表明合成纳米粒子的纳米结构受不同温度电炉顺序的影响。
