李亚栋组最新综述<Nano Today>多种结构双金属纳米材料的合成及催化性能
|
|||
|
双金属纳米材料，由于两种金属的协同作用，出现了新的物理和化学属性，从而具有很多新的应用，其中研究最多的就是其催化性能。本文综述了双金属纳米材料合成与属性的最新进展，从王冠-宝石结构、空心结构、核壳结构、合金等等各种结构双金属的可控合成入手，讨论了表面结构、组成、尺寸和形貌对其催化性能的影响，并对双金属纳米材料的研究前景进行了展望，全文19页，引文150篇。 Bimetallic nanomaterials have raised more and more significant concern from worldwide researchers in recent years because their new physical and chemical properties derived from synergistic effects between the two metals are highly desirable for specific technological applications, especially for catalytic applications. This review article provides an overview of recent developments in synthesis and properties of bimetallic nanomaterials. First, we summarize recent contributions on developing strategies for the controllable synthesis of bimetallic nanomaterials with various architectures including crown-jewel structure, hollow structure, heterostructure, core–shell structure, alloyed structure and porous structure. Then, we discuss how the microstructural parameters such as surface structure, composition, size, and morphology (crystal facet) influence catalytic properties of bimetallic nanomaterials. Finally, we conclude with our personal perspectives of future research in bimetallic nanomaterials.  [ Last edited by dut_ameng on 2012-9-12 at 00:20 ] |
