采用电泳沉积法在多孔阳极氧化铝膜的纳米孔道中成功制备了有序的纳米TiO 2纳米线阵列。利用扫描电子显微镜和X射线衍射仪对材料进行了表征。通过定量降解罗丹明B染料溶液来表征TiO 2纳米线阵列的光催化活性。与溶胶-凝胶法制备的TiO 2纳米线阵列和薄膜相比，电泳法制备的TiO 2纳米线阵列具有更高的光催化活性，这主要归因于其比表面积和能隙较大。
Ordered anatase TiO2nanowire arrays have been successfully fabricated in the nanochannels of porous anodic alumina membrane by electrophoretic deposition. The as-grown materials were characterized by using scanning electron microscope and power X-ray diffraction. The photocatalysis activities of TiO2nanowire arrays were characterized by quantifying the degradation of Rhodamine B dye solution. Compared with TiO2nanowire arrays and thin film by using sol–gel deposition, higher photocatalytic activity of TiO2nanowire arrays by using electrophoretic deposition is obtained and mainly attributed to larger surface areas and greater energy gap.
