title: Titania nanocrystals and adsorptive nanoporous polymer composites: an enrichment and degradation system.
abstract: Composites of titania nanocrystals and adsorptive nanoporous polymers are synthesized via a two-step solvothermal pathway. These composites are developed as bifunctional materials for both the adsorption of organic compounds and photocatalysis, providing an enrichment and degradation system for the removal of environmental pollutants. The anatase-phase titania nanoparticles are homogeneously dispersed in the matrix of the nanoporous polymers. The composites exhibit nanoporous structures, high surface areas, and excellent stabilities. Experimental results show that the composites have excellent adsorptive properties for organic compounds in water and air and high photocatalytic activities under UV irradiation. These bifunctional materials may have promising applications in environmental protection.
