采用草酸（H2 C2 O 4）刻蚀、电沉积和煅烧的方法制备了致密葡萄状的二氧化钛（Ti）包覆氧化铋（Bi 2 O3）阳极，并对其光电催化性能进行了研究。结果表明，Bi 2 O3涂层孔隙丰富，与蜂窝状基体结合良好。Bi 2 O3涂层的特征形貌表明电极在降解过程中是稳定的。采用Bi 2 O3/Ti电极对酸性橙橙子7进行电解、光催化氧化和光电催化氧化降解。在420 nm可见光照射下，光电催化过程的准一级动力学参数（Kapp）是电解和光催化氧化之和的1.15倍。结果表明，电解和氧化的协同作用使Bi 2 O3/Ti电极具有良好的光电催化性能。
Compact and grape-like bismuth oxide (Bi2O3) coated titania (Ti) anode was prepared by oxalic acid (H2C2O4) etching, electrodeposition and calcination in order to explore its photoelectrocatalytic activities. The Bi2O3coating was demonstrated to be full of pores, and a good combination between Bi2O3layer and honeycomb-like Ti substrate was observed by scanning electron microscopy. The characteristic morphology of Bi2O3coating indicated that the electrode is stable during degradation. The Bi2O3/Ti electrode was used in oxidative degradation of Acid Orange 7 by electrolysis, photocatalytic oxidation and photoelectrocatalytic oxidation processes. The pseudo-first order kinetics parameter (Kapp) of photoelectrocatalytic process was 1.15 times of the sum of electrolysis and photocatalytic oxidation under visible light irradiation at 420nm. The results indicated that the synergy of electrolysis and photocatalysis lead to an excellent photoelectrocatalytic property of the Bi2O3/Ti electrode.
