Chem. Soc. Rev.最新综述：胶体化学途径制备双金属纳米晶的形貌控制
|
|||
|
最新一期的Chem. Soc. Rev.刊发了由北大和美国圣母大学两个课题组合作撰写的题为Shape control of bimetallic nanocatalysts through well-designed colloidal chemistry approaches的综述，详细的总结了通过胶体化学途径制备双金属纳米晶中形貌控制的进展。文章16页，引文63篇。 Synthesis of bimetallic nanomaterials with well controlled shape is an important topic in heterogeneous catalysis, low-temperature fuel cell technology, and many other fields. Compared with monometallic counterparts, bimetallic nanocatalysts endow scientists with more opportunities to optimize the catalytic performance by modulating the charge transfer between different metals, local coordination environment, lattice strain and surface element distribution. Considering the current challenges in shape controlled synthesis of bimetallic nanocatalysts, this tutorial review highlights some significant achievements in preparing bimetallic alloy, core–shell and heterostructure nanocrystals with well-defined morphologies, summarizes four general routes and some key factors of the bimetallic shape control scenarios, and provides some general ideas on how to design synthetic strategies to control the shape and exposing facets of bimetallic nanocrystals. The composition and shape dependent catalytic behaviours of bimetallic nanocrystals are reviewed as well. .  GA.gif [ 来自科研家族 材料家族 ] |
