Multilevel structured porous polymer particles, consisting of submicron hollow cavities and crosslinked shell with interconnected mesopores, are specially designed, prepared and served as super-adsorbent materials. As a proof of concept, we applied the carboxylate-functionalized hollow particles as selective adsorbent for the removal of basic dye methylene blue. Because of their extremely high functional group density and unique strucutre, the as-designed particles show super adsorption capacity (1603 mg g−1 for methylene blue), ultra fast adsorption/desorption rates, facile separation and easy regeneration.
