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,形成的是纳米管结构.而在较低的负电位时形成的是纳米线.在硝酸根离子的电催化实验中,相比于薄膜,纳米管的催化性能受氢气析出的影响较小.在空气中放置6个月后,二元金属纳米管被氧化成均一相的氧化物纳米管. Binary metal nanotubes made of palladium and copper nanoparticles are prepared in the alumina template by electrodeposition The competition between the diffusion of the metal ions and the deposition process determines whether the final product is nanotubes or nanowires. At higher negative potentials, the growth is controlled by diffusion and metal ions are consumed at the edges of the nanotubes, forming nanotube structures, whereas at lower negative potentials, nanowires are formed. In the electrocatalysis of nitrate ions In the experiment, the catalytic performance of the nanotubes was less affected by the evolution of hydrogen than that of the films.After 6 months in air, the binary metal nanotubes were oxidized to oxide nanotubes of uniform phase.
