Presentation Transcript

  1. A versatile strategy to the selective synthesis of Cu nanocrystalsand the in situ conversion to CuRunanotubes

  2. Palladium/tin bimetallic single-crystalline hollow nanospheres 合成（油胺中一锅法合成）： SnCl2∙H2O,Pt(acac)2和十二烷基二甲基溴化胺(DDAB)溶解在油胺(OAm)等到亮黄色透明溶液 十八烯(ODE)和油胺于25ml三口瓶，加热至300 将1中黄色液体注射到2中，热液即变黑色 15min后反应停止，冷却至室温 用乙醇洗三次分散到环己烷中。

  3. 表征：TEM/HRTEM,STEM,XRD,EDS Pd2+/Pd比Sn2+/Sn潜能高，易于氧化， 且Pd生成后可以促进Sn2+的还原 低温下腐蚀速率比高温下低。 DDAB是关键因素，不含DDAB不能形成穴。进一步讲，Br作为关键因素

  4. In SituGrowth of Catalytic ActiveAu-PtBimetallic Nanorods inThermoresponsiveCoreShellMicrogels
