雙金屬納米材料,由于兩種金屬的協(xié)同作用,出現(xiàn)了新的物理和化學屬性,從而具有很多新的應用,其中研究最多的就是其催化性能。本文綜述了雙金屬納米材料合成與屬性的最新進展,從王冠-寶石結(jié)構(gòu)、空心結(jié)構(gòu)、核殼結(jié)構(gòu)、合金等等各種結(jié)構(gòu)雙金屬的可控合成入手,討論了表面結(jié)構(gòu)、組成、尺寸和形貌對其催化性能的影響,并對雙金屬納米材料的研究前景進行了展望,全文19頁,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.
