The formation process and the photocatalytic activity of the oxide nanohole arrays were evaluated. The fabrication of the various oxide nanohole arrays with various hole diameter were succeeded by immersion of the anodic alumina in metal fluoride solutions. The crystal structure of titania nanohole arrays as prepared was amorphous. As titania nanohole array annealed at 773 K, the crystal structure became anatase. Photocatalytic activity of titania nanohole arrays were estimated by the photodecomposition properties of methylene blue and acetaldehyde. The activity of photodecomposition of methylene blue and acetaldehyde was increased with heat treatment temperature. Titania nanohole array annealed at 1173 K showed the highest photocatalytic activity. This result was caused by that the specific surface area of titania nanohole array was almost constant with heat treatment. Titania nanohole array with various hole diameter was prepared. The sample with the 250 nm and 200 nm diameter showed the highest photocatalytic activity.

对氧化物纳米孔阵列的形成过程和光催化活性进行了评价。通过将阳极氧化铝浸渍在金属氟化物溶液中，成功地制备了具有不同孔径的各种氧化物纳米孔阵列。所制备的二氧化钛纳米孔阵列的晶体结构为非晶态。在773 K退火后，TiO2纳米孔阵列的晶体结构发生了变化.通过亚甲基蓝和乙醛的光催化降解性能评价了二氧化钛纳米孔阵列的光催化活性。随着热处理温度的升高，光分解亚甲基蓝和乙醛的活性增加。在1173 K退火的TiO2纳米孔阵列具有最高的光催化活性。这是由于二氧化钛纳米孔阵列的比表面积在热处理过程中基本保持不变。制备了不同孔径的二氧化钛纳米孔阵列。粒径为250 nm和200 nm的样品具有最高的光催化活性。
