摘 要: | 本文采用一锅法制备钯铜纳米材料( PdCu),并对PdCu纳米颗粒形貌、成分及微观结构进行表征。 X射线衍射仪( XRD)和透射电子显微镜( TEM)结果表明,PdCu纳米颗粒呈单分散的复杂多枝状结构。多枝状PdCu颗粒的产率高达90%左右,其粒径大小约为(30.85±8.68) nm。乙醇的循环伏安法与计时安培法测试表明PdCu多枝合金有良好的乙醇电催化性能和循环稳定性。

Abstract: | In this paper, a PdCu nanomaterial had been synthesized via a simple Wet Chemical method. The morphology, microstructures and chemistry of PdCu were characterized by X-ray diffraction(XRD) and transmission electron microscopy (TEM). The results showed that PdCu nanoparticles were monodisperse spherical and multibranched shapes. The yield of branched PdCu were approximately 90%. The average size of branched PdCu nanoparticles was ( 30. 85 ± 8. 68 ) nm. PdCu nanocrystals showed superior electrocatalytical performance with excellent cyclic stability. |
