摘要：

Two kinds of TiO2 nanostructures, i.e., TiO2-coated alumina membranes and TiO2-coated Ni nanowires, were prepared by combining different kinds of porous alumina, template-directed electrodeposition and atomic layer deposition. The photocatalytic activities of the nanostructures were tested with methylene blue degradation under UV illumination. All structures showed photocatalytic activity, and the efficiency of the photocatalytic performance was found to be a strong function of the dimensions of the nanostructure.
