An Efficient Method to Form TiO₂/CdS Nanotube Arrays Using Anodic Aluminum Oxide (AAO) Templates

Abstract:

In this paper, a simple, efficient and environmental friendly method was proposed to fabricate TiO₂/CdS nanotube arrays. The composite nanotubes with a core-shell coaxial structure were fabricated via a simple method of liquid deposition and double diffusion using anodic aluminum oxide (AAO) templates. The photocatalytic properties of the nanotube arrays (TiO₂, TiO₂/CdS) were confirmed by the degradation of methyl orange (MO) under UV irradiation. Compared to bare TiO₂ nanotube arrays, TiO₂/CdS composite nanotube arrays showed improved photocatalytic performance: The degradation efficiency of TiO₂/CdS and TiO₂ nanotube arrays towards methyl orange was 65% and 39%, respectively.
