Self-organized, free-standing TiO2 nanotube membrane for flow-through photocatalytic applications

Abstract

In the present work we show a simple and robust fabrication process of a dense and free-standing membrane consisting of vertically oriented, both-side-open TiO2 nanotubes. This membrane structure allows direct, size-selective, flow-through photocatalytic reactions with a very high efficiency. © 2007 American Chemical Society.
