NanotechnologyV 1505 Hexagonal-Close-Packed, Hierarchical Amorphous TiO2 Nanocolumn Arrays:
Transferability, Enhanced Photocatalytic Activity, and Superamphiphilicity Without UV Irradiation. — The title nanocolumn array is prepared by pulsed laser deposition using a polystyrene colloidal monolayer as a template (6.7 Pa background O2 pressure) and characterized by FE-SEM, TEM, and XPS. The nanostructured TiO2 array can be transferred to almost any desired substrate during the removal of the poly-styrene colloidal monolayer in an organic solution. It exhibits both enhanced superam-phiphilicity without further UV irradiation and photocatalytic activity, giving the TiO2 surface an excellent self-cleaning effect. — (LI, Y.; SASAKI, T.; SHIMIZU, Y.; KOSHIZAKI*, N.; J.
