Summary

Story summary

A photocatalytic film using Cz-AQ enables low-energy, simple operation for resource-limited areas.
When exposed to water and sunlight, Cz-AQ generates long-lived oxygen-centered organic radicals (OCORs) that kill bacteria, degrade pollutants, and prevent new bacterial growth for at least five days.
The film can be reused over 50 times without losing stability, supporting cost-effectiveness and global water-safety improvements.
