摘　　要：采用阳极氧化法制备转盘式TiO_2阳极,设计并开发了转盘式光催化燃料电池(PFC),探讨了圆盘转速对PFC中染料降解效果的影响。实验结果表明:随着圆盘转速的提高,污染物和光电界面反应产物的传质作用得以强化,罗丹明B降解率提高;在圆盘转速为1 600 r/min、反应时间为60 min的条件下,罗丹明B降解率达90.8%,是圆盘转速为0 r/min时的8.5倍;光电流也随着圆盘转速的提高而提高,但提高幅度远小于罗丹明B降解率的提高幅度;同时,加强传质作用后再外加电压对PFC催化降解性能的提高作用有限。The rotating TiO2 anode was prepared by anodic oxidation method,and the rotating disk photocatalyst fuel cell（PFC）was designed and developed. The effect of rotating speed of the disk on dye degradation was investigated. The experimental results showed that：With the increase of rotating speed,the degradation rate of Rhodamine B was increased because of the enhancement of mass transfer between contaminants and photoelectric interface reaction products;Under the conditions of rotating speed 1 600 r/min and reaction time 60 min,the degradation rate of Rhodamine B was 90.8%,which was 8.5 times of that at 0 r/min;The photocurrent also increased with the increase of rotating speed,but the increasing range was much less than that of Rhodamine B degradation rate;Meanwhile,the applied voltage slightly improved the degradation performance of the mass transfer enhanced PFC.
