| 中文摘要: |
| 采用诱导法制备空心三元PdPtCu纳米材料,利用透射电镜(TEM)、扫描电镜(SEM)和X射线衍射(XRD)对其形貌、组成和结构进行表征,并在碱性条件下测试其对乙醇氧化的电催化性能。结果表明,以氧化铜为诱导剂制备的三元PdPtCu纳米材料主要呈空心结构,且其形貌和组成可控;Pd3Pt@Cu,PdPt@Cu和PdPt3@Cu三种材料的质量电流密度分别为8 510 A·g-1,9 270 A·g-1和5 490 A·g-1,无论是质量活性还是稳定性,均明显优于商业Pd/C和商业Pt/C催化剂。 |
| 英文摘要: |
| Hollow ternary PdPtCu Nanomaterial has been successfully prepared by induction synthesis. The morphology, composition and structure are characterized by using transmission electron microscope (TEM), scanning electron microscope (SEM) and X-ray diffraction (XRD). The electrocatalytic properties for ethanol are tested in alkaline medium. The results show that the ternary PdPtCu nanomaterials obtained with the copper oxide as the inducing agent are mainly featured with hollow structure,and their morphology and composition are controllable; The mass electric current densities of Pd3Pt@Cu, PdPt@Cu and PdPt3@Cu are respectively 8 510 A·g-1,9 270 A·g-1 and 5 490 A·g-1, which have shown superior performance both in mass activity and stability compared with the commercial Pd/C and commercial Pt/C catalysts. |
