二氧化钛纳米晶体和吸附性纳米多孔聚合物的复合材料是通过两步溶剂热途径合成的。这些复合材料被开发为双功能材料，用于有机化合物的吸附和光催化，为去除环境污染物提供富集和降解系统。锐钛矿相二氧化钛纳米粒子均匀分散在纳米多孔聚合物的基质中。该复合材料具有纳米多孔结构、高表面积和优异的稳定性。实验结果表明，该复合材料对水和空气中的有机化合物具有优异的吸附性能，并且在紫外照射下具有较高的光催化活性。这些双功能材料在环境保护方面可能具有广阔的应用前景。
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.
