Fabrication of wire mesh-supported ZnO photocatalysts protected against photocorrosion

- Novel supported ZnO nanoflowers for the photodegradation of organic contaminants.
- Catalytic stability was evaluated by both the catalytic activity and ZnO losses.
- Ag-doping increases initial activity, but deactivation still persists.
- Dip-coating with polysiloxane provokes catalyst photostabilisation.
- Surface Si/Zn atomic ratios around 1 provided optimal activity and stability.
