Preparation and characterization of TiO2/HZSM-11 zeolite for photodegradation of dichlorvos in aqueous solution

- TiO2/HZMS-11(30%) sample degraded efficiently aqueous solutions of dichlorvos.
- TiO2/HZSM-11 samples did not show evidence of rutile phase.
- HZMS-11 (support) is not active by itself in the degradation of dichlorvos.
- The catalyst can be reused without activity loss during at least four cycles.
