摘要：

以聚合前驱体方法制备了Ti/SnO₂平板电极，用SEM和XRD表征了电极表面涂层形貌及结构。以自制Ti/SnO₂电极为阳极，电解催化氧化法处理100 mg/L的含酚废水，试验表明电催化系统能够产生羟基自由基，自制Ti/SnO₂电极具有良好的催化活性和使用寿命。当电流密度为0.01 A/cm²、极板间距为14 mm、初始pH为4，电解催化时间50 min后，出水苯酚去除率几乎为100%。

Abstract:

The Ti/SnO₂ plate electrode has been prepared by polymeric precursor process. The surface coatingsform and structure of the electrode are characterized by scanning electron microscope(SEM) and X-Ray Diffraction (XRD),respectively. The results show that the homemade Ti/SnO₂ electrode has good catalytic activity and service life. Using this homemade Ti/SnO₂ electrode as anode,the results of tests show that the electrolytic catalysis system can produce ·HO. 100 mg/L of phenol-containing wastewater is to be treated,when the current density is 0.01 A/cm²,plate spacing 14 mm,initial pH 4,and electrolysis catalysis time 50 min,the effluent phenol removing rate is almost 100%.

Key words: Ti/SnO₂, electro-catalysis, phenol
