In order to achieve better photocatalytic performance, rutile dispersion in anatase was obtained from titanium isopropoxide (TIP) in a highly acidic solution at room temperature. Further hydrothermal treatment at 130 oC increased the crystallinity of titania. TEM revealed that the nanosized titania particles mainly consisted of granular anatase and rodlike rutile. These nanocrystals were applied onto cotton fabrics, and achieved a durable and satisfying protection against UV radiation. Preliminary experiments convinced us on the better photocatalytic behavior than the pure anatase phase.
