开发具有上级活性的光电催化剂对水的净化具有重要意义。本文采用电化学沉积和电泳沉积相结合的方法制备了氧化石墨烯（GO）包裹的Ti/PbO 2光阳极。与Ti/PbO 2参比电极相比，该复合电极对活性艳蓝KN-R的光电催化降解效果更好。实验结果表明，氧化石墨烯（GO）包裹Ti/PbO 2光阳极的高效光电转换性能可归因于较低的电荷转移电阻、较大的电化学活性面积和较高的诱导电子/空穴分离效率。此外，在光电催化过程中，可以观察到显着的光电协同效应的氧化石墨烯（GO）包裹的Ti/PbO 2光阳极。
The development of semiconductor-based photoelectrocatalysts with superior activity is of great importance for water purification. Here, we fabricated graphene oxide (GO)-wrapped Ti/PbO2 photoanodes by combination of electrochemical deposition and electrophoretic deposition process. The as-obtained composite electrodes showed better performance for photoelectrocatalytic (PEC) degradation of reactive brilliant blue KN-R, as compared with that of Ti/PbO2 reference. Experimental results demonstrated that the efficient PEC performance of graphene oxide (GO)-wrapped Ti/PbO2 photoanodes could be ascribed to the low charge transfer resistance, large electrochemical active areas, and high separation efficiency of induced electrons/holes. Furthermore, a significant photoelectric synergy effect can be observed for the graphene oxide (GO)-wrapped Ti/PbO2 photoanodes during the photoelectrocatalytic process.
