Controllable synthesis of well-aligned CuO nanotube arrays using porous alumina templates
Abstract
In order to further enhance the performance of CuO in currently existing applications, well-aligned CuO nanotube arrays with different diameters were fabricated. During the synthesis process, porous anodic alumina films were fabricated, and then the synthesis of CuO nanotube arrays was realized by using the obtained porous anodic alumina films as templates. The morphology and structure of the obtained products has been confirmed by field-emission scanning electron microscopy, transmission electron microscopy and X-ray diffraction measurements. Due to the large surface area of the synthesized products, the prepared CuO nanotube arrays may have potential applications in catalyzing and gas sensing area.
