摘要：
We report the fabrication of gold nanotube arrays by means of a direct electrodeposition method utilizing nanochannel alumina templates. The observations by SEM and TEM show that gold nanotubes were obtained within the alumina template with different pore diameters. The mechanism related to the morphology formation is discussed. The sensing applications of the gold nanotube arrays have been investigated by using square-wave voltammetry and cyclic voltammetry. The gold nanotube arrays exhibit low-potential electrocatalytic detection of hydrogen peroxide with high sensitivity and show promise for biosensing applications.
