使用具有547个孔道的微结构聚合物预制棒，建立了一种新型的光催化降解有机废水体系。通过微波热处理技术，TiO2纳米晶薄膜附着在光催化反应体系的孔道中。使得反应体系增加光催化剂和溶液的接触面积，提高了光催化效率，同时加入强氧化剂 H2 O2来协同TiO2用于光催化分解有机染料罗丹明B；研究了 H2 O2的浓度及RB的初始浓度对光催化的影响，表明该反应体系在光照的条件下具有降解有机染料的能力。

A new type of photocatalytic degradation of organic wastewater system based on microstructured polymer optical fiber (MPOF ) preform with 547 pores was designed, constructed,and each channel was covered with TiO2 film. The photocatalytic active TiO2 nanocrystal film that covered on the channels of the MPOF preform was obtained by microwave processing.Thus the inner surfaces of pores,used as the reactors for the photocatalyst,was expected to increase the photocatalyst-liquid contact area, and enhance the photocatalytic efficiency.Moreover,hydrogen peroxide was added as strong oxidant to synergy degradating Rhodamine B in solution.The effects of different initial hydrogen peroxide concentration and the dye concentration were investigated.The results indicated that the photocatalysis activity of the system was proved to possess the ability of degradating organic dye in the light.
