摘要：

Porous polymer particles with multilevel structures consisting of submicron-sized hollow cavities and interconnected mesopores within the crosslinked shell were designed and prepared. An extremely high density of anhydride groups in the crosslinked shell can be conveniently converted into versatile functional groups for the adsorption of hazardous pollutants. As a proof of concept, we utilized carboxylate-functionalized hollow particles as a selective adsorbent for the removal of the basic dye methylene blue and found that these particles exhibited a very high adsorption capacity (1603 mg g(-1)). Furthermore, the hollow structure, highly interconnected mesopores and rigid shell of the particles not only endow the adsorbent with fast adsorption/desorption rates but also facilitate their facile separation and easy regeneration. We believe that these porous polymer particles have great potential for applications in many fields, including as adsorbents, catalyst supports and matrices for the binding of sensitive materials.
