Heterogeneous Catalysts Catalyzed Photo‐Atom Transfer Radical Polymerization (Photo‐ATRP)

Abstract Photo‐ATRP technique has garnered significant attention due to its multitude of advantages, including its ability to be conducted under mild reaction conditions, user‐friendly nature, and exceptional efficiency in polymerization. The heterogeneous photocatalysts not only exhibit exceptional quantum efficiency, but also possess a versatile bandgap that can be finely adjusted to accommodate a wide range of absorption wavelengths within the visible light spectrum, thereby emphasizing their potential for efficient recovery and reuse. The utilization of a variety of heterogeneous photocatalysts in photo‐ATRP presents notable benefits for numerous applications, such as the lack of any remaining substances, simplicity in usage, and potential for reuse. This review focuses on recent progress in photo‐ATRP utilizing a wide variety of heterogeneous photocatalysts, encompassing metal semiconductor nanoparticles, quantum dot, upconversion nanoparticles, metal–organic frameworks, covalent–organic frameworks, conjugated microporous polymers, hypercrosslinked polymer, and carbon‐based materials.
