Highly Ordered TiO2 Macropore Arrays as Transparent Photocatalysts

Figure 1

(a) SEM of PS sphere monolayer on glass substrate, the insect image is FFT of the SEM image of PS monolayer. (b, c, and d) SEM images of 2D TiO2 ordered arrays with magnification of 2500x, 40000x, and 140000x, respectively. The insect image of Figure 1(b) is FFT of the SEM image of the TiO₂ arrays. (e, and f) Photographs of large-scale 2D TiO₂ ordered arrays under different incident angles of light.
