Photocatalytic detoxification of a sulfur mustard simulant under realistic conditions by imidazoline-based porous organic polymer composites

This is the authors' abstract. We don't add key points for this paper.

Porous materials have recently been explored as highly effective photosensitizers for the photocatalytic detoxification of sulfur mustard. However, most porous material-based photosensitizers are reliant on heavy-metal effects and require non-realistic light sources and O2-enriched atmosphere to generate reactive oxygen species (ROS). To overcome such health problems and practical limitations, we here report a porous organic polymer (POP) photosensitizer (KUP-3) with a protonated imidazoline core, notably showing the generation of types I and II ROS. Owing to its robust framework, KUP-3 can be incorporated into fabrics or melamine sponges via in situ polymerization. The composite-based photocatalysts ([email protected] and [email protected]) exhibit protective and decontamination effects along with the photocatalytic detoxification, even under sunlight irradiation and ambient atmosphere, which is beneficial in real-world applications. This study demonstrates the design and fabrication strategy of a class of POP-based composite materials to enable practical applications for photocatalytic detoxification.
