Study of ZnO-photocatalyst deactivation during continuous degradation of n-hexane vapors

- The ZnO-photocatalyst deactivation occurs in less than 14 h.
- Photocatalytic process produces several types of n-hexane byproducts.
- Ketones and aldehydes were identified as byproducts on the ZnO/Perlite surface.
- Water accumulation plays an important role on photocatalytic deactivation.
