Nanoporous polymer monoliths as adsorptive supports for robust photocatalyst of Degussa P25.

Nanoporous polymer monolith-supported Degussa P25 as adsorptive photocatalysts was successfully synthesized by a simple solvothermal polymerization of polymeric precursor in the presence of P25 fine powder. TiO(2) nanoparticles distribute homogeneously in the matrix of nanoporous polymer monoliths. The monolithic morphologies benefit separation and recovery in practical applications. In addition, the composites reveal high BET surface area and large pore volume, thus exhibiting excellent adsorptive properties for organic compounds, which is propitious to enrichment and photodegradation of the organic target. The synthesis of adsorptive supports for immobilization of powdery photocatalysts would show significant improvements in both practical use and degradation efficiency of photocatalysis in environmental protection.
