Magnetically recyclable polymer photocatalytic materials for sustainable photocatalysis

Abstract The production of easily separable and recoverable photocatalytic materials remains a critical challenge in achieving sustainable photocatalysis. Here, we have created a hybrid material consisting of photocatalytic polymers encapsulating magnetite nanoparticles. These nanoparticles exhibit excellent performance in oxidative hydroxylation of both boronic‐acid‐ and boronic‐acid‐pinacol‐ester‐containing substrates. Moreover, these nanoparticles can be easily recovered and regenerated from the reaction medium via a simple magnetic separation technique. Extremely high efficiency has been maintained over multiple cycles, by recycling the magnetic photocatalyst. © 2025 The Author(s).
