Interfaced titanium dioxide anatase-rutile nanocomposites by thermohydrolysis in presence of small amounts of Sn(IV) and their photocatalytic properties

- We produced TiO2 anatase-rutile nanocomposites with oriented interfaces.
- We controlled the phase ratio by using small amount (<1%) of Sn(IV).
- The photocatalytic properties are optimized by phase ratio tuning.
