Titanium dioxide(TiO_2) photocatalyst has attracted much attention for the effective cleanup of various environmental pollutants. However, its practical application is limited because of the difficulty to deal with small TiO_2 particles. Hence, recent research has been directed at immobilizing TiO_2 powders onto a supporting material. This research provided a lot of practical, interesting results for the preparation and environmental applications of paper-like composites containing TiO_2 and other powder materials which were supported on inorganic fiber matrix. The ceramic fiber/TiO_2 composites were successfully prepared by a papermaking technique with a dual polyelectrolyte system whereby high formability and productivity were achieved. Indoor/atmospheric pollutants and endocrine-disrupting chemical in water were photocatalytically decomposed by the TiO_2 composites under weak UV irradiation. Tailoring the combination of TiO_2 and zeolite adsorbent in the composites accelerated the photodegradation of various pollutants. Catalyst mixture in and void structure of paper composites made a great contribution to the enhancement of photocatalytic efficiency from a practical viewpoint. The porous, flexible and easy-handling fiber/TiO_2 composites would be expected as a promising material with effective photocatalytic performance for environmental applications.

二氧化钛（TiO_2）光催化剂因其对各种环境污染物的有效净化而受到广泛关注。但由于难以处理细小的TiO_2颗粒，限制了其实际应用。因此，最近的研究方向是将TiO_2粉末固定在支撑材料上。本研究为二氧化钛和其他粉末材料在无机纤维基体上的纸状复合材料的制备和环境应用提供了许多实用、有趣的结果。采用双聚电解质体系造纸技术成功制备了陶瓷纤维/TiO_2复合材料，获得了较高的成形性和生产率。在弱紫外照射下，TiO_2复合材料光催化降解室内/大气污染物和水中内分泌干扰物。复合材料中TiO_2与沸石吸附剂的选择性组合加速了各种污染物的光降解。从实际应用的角度来看，纸复合材料的催化剂混合物和孔隙结构对提高光催化效率有很大的贡献。多孔、柔韧、易处理的纤维/TiO_2复合材料是一种具有良好光催化性能的环保材料。
