一步法电沉积钯铜二元金属纳米管(英文)被引量:1
《中国科学技术大学学报》2010年第9期957-963,共7页洪勋 王冠中 祝巍 沈小双 
Supported by Natural Science Foundation of China(10574122,50772110,50721091);the National Basic Research Program of China(2006CB922000,2007CB925202,2009CB939901);KJCX2.YW.W06-3 of CAS
由钯和铜纳米颗粒组成得二元金属纳米管通过电沉积的方法在氧化铝模板中被制备出来.金属离子的扩散和沉积过程的竞争决定了最终的产物是纳米管或者是纳米线.在较高负电位下,其生长受扩散控制,金属离子在纳米管的边缘被消耗,形成的是纳...
