Controllable fabrication of TiO2 anatase/rutile phase junctions by a designer solvent for promoted photocatalytic performance.

ABSTRACT

Herein, novel coin tree-like TiO2 moieties with lots of anatase-rutile phase junctions were constructed by a general, simple, and environmentally friendly strategy. The anatase/rutile ratios can be easily tuned by changing the ratios of the two H-bond donors. Owing to this featured shape, the TiO2 sample displays robust photocatalytic activity and better stability.
