In this work, for the first time, an anodic TiO2 nanotube layer of large area (~50 cm2) was used for photocatalysis in the gaseous phase. Hexane was chosen as model pollutant. The nanotube layer showed superior efficiency compared to a reference TiO2 layer of the same thickness composed of immobilized P25 nanoparticles. An additional TiO2 coating of the nanotube layer produced by atomic layer deposition did not enhance the photocatalytic degradation of hexane due to a decrease in the active surface area, in contrast to liquid state photocatalysis under applied external potential.

放大阳极TiO 2纳米管层以进行气相光催化
在这项工作中,首次将大面积(〜50 cm 2)的阳极TiO 2纳米管层用于气相光催化。选择己烷作为模型污染物。与由固定的P25纳米粒子组成的相同厚度的参比TiO 2层相比,纳米管层显示出更高的效率。与在施加的外部电势下的液态光催化相反,由于原子表面积的减少,通过原子层沉积产生的纳米管层的另外的TiO 2涂层并未增强己烷的光催化降解。
