Synergetic promotion on photoactivity and stability of W18O49/TiO2 hybrid

- W18O49/TiO2 hybrid achieves significant synergetic promotion on the photoactivity and photostability.
- W18O49(10 wt%)/TiO2 and W18O49(90 wt%)/TiO2 show 2.43 (2.64) and 1.31 (1.52) times higher activity than the calculated baseline in degradation of MO (phenol), under UV-vis and visible light, respectively.
- Well-matched band structure between W18O49 and TiO2 enhances the photo-induced charge separation and transfer.
- ·O2− and hole, especially the former, are the active species involved in the photodegradation.
