摘　　要：采用阳极氧化法制备了I掺杂TiO2纳米管阵列(I-doped TiO_(2) Nanotubes Arrays, ITNA)光阳极,该电极表现出比TNA更加优异的降解性能.将ITNA与Pt电极组合得到的平面光催化燃料电池(planar Photocatalytic Fuel Cell, p-PFC)在亚甲基蓝(Methylene Blue, MB)浓度为6 mg·L^(–1)、极板间距为1.0 cm时脱色率达到最大,为93.1%. MB的降解发生在ITNA表面,为限速步骤.对比了p-PFC和传统PFC结构对MB和其他有机物的降解, p-PFC中h+和·OH的产生和传质优于其他结构,具有更高的光催化性能.The photoanode of I-doped TiO_(2) nanotube arrays(ITNA) prepared by anodization exhibited better degradation performance than TNA. The planar photocatalytic fuel cell(p-PFC) obtained by combining ITNA and Pt electrodes achieved a maximum decolorization rate of 93.1% when the concentration of methylene blue(MB) was 6 mg·L^(–1) and the electrode plate spacing was 1.0 cm. The degradation of MB occurred on the surface of ITNA, which was a rate-limiting step. Compared to other structures, p-PFC had a higher photocatalytic performance and better production of h+ and ·OH, while degrading MB and other organics.
