聚合物载体固定化TiO_2光催化剂的研究进展

Research progress of immobilization of TiO_2 photocatalyst by polymer carriers

将TiO2光催化剂固定到聚合物载体中制备TiO2/聚合物膜是解决其难回收、易团聚的有效方法。归纳分析了国内外在TiO2/聚合物膜的孔径和孔隙率、光催化剂的泄漏问题和聚合物载体的抗损伤性等3个方面的最新研究进展,对新的研究方向进行了展望,为聚合物载体固定化TiO2光催化剂的工业化应用提供了有益思路。

Immobilizing TiO2 photocatalyst into polymer carriers to prepare TiO2/polymer film is an effective method that can solve the problems of TiO2 such as hard to be recycled and easy agglomeration. The latest re- search progress of TiOJpolymer film in China and abroad were summarized and analyzed from aspects of pore diameter and porosity, leakage of photocatalyst, and anti-injury ability of polymer carriers; besides, the novel research direction was also mer carriers immobilized prospected, which provided useful train of thought for industrialized application of poly- TiO2 photocatalyst.
