- •
Ease synthesis of mesoporous WO3–TiO2 nanocomposites were performed.
- •
XRD and Raman spectra confirmed that monoclinic and triclinic of WO3 was detected.
- •
The prepared photocatalysts were evaluated for photodegradation of imazapyr.
- •
It could be completely degraded of imazapyr within 120 min under UV light.
- •
Under visible light, 0.5%WO3–TiO2 is the optimum with 46% photocatalytic efficiency.
