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 nanomaterialhad been synthesized via a simple Wet Chemical method. The Mmorphology, microstructures and chemistry of PdCuwere characterizedby 。The characterization results of X-ray diffraction(XRD)and transmission electron microscopy (TEM). The results showed thatPdCunanoparticles were monodisperse sphericaland multibranched shapes.The yield of Branched branched PdCuwere approximatelyabout90percent%.The average sizesof branched PdCu nanoparticles was 30.85±8.68nm.PdCunanocrystalsshowed superior electrocatalytical performance with excellent cyclic stability.
Keywords Pd-Cu；TEM；XRD；superior electrical catalytical performance；cyclic stability
