Preparation and photoelectric property of TiO2 nanoparticles with controllable phase junctions

- A series of bicrystalline TiO2 nanoparticles with different ratio of controllable phase junctions between anatase and rutile were synthesized successfully using ionic liquid-assisted method by hydrolysis of TiCl4.
- The spatial separation capacity of photogenerated charge carriers and photocatalytic activities of the samples with different ratio of controllable phase junctions were evaluated systemically.
- The best photocatalytic activity for MO degradation can reach above 99% at the sample with 27.4% rutile which also has the best photoelectric property compared with other samples.
