摘要

采用阳极氧化法制备了I掺杂TiO2纳米管阵列(I-doped TiO2 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.

Abstract

The photoanode of I-doped TiO2 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–1and 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.

Key words： planar photocatalytic fuel cell (p-PFC); TiO2 nanotubes arrays (TNA); I-doped; methylene blue (MB)
