TiO2 array films with controllable morphology.
Titanium dioxide films with large-area 2D ordered pore structure were prepared on glass substrate via a sol dip-coating latex template method. By simply controlling the concentration of the precursor sol, TiO2 array films with different morphologies, such as hollow sphere shell, bowl, pot, and ring arrays were obtained. Such films have large-scale periodic feature and large specific areas, which is promising to be useful in the optical, gas-sensing, catalysis applications.
