摘　　要：以聚合前驱体方法制备了Ti/SnO_2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/SnO_2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/SnO_2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p H为4,电解催化时间50 min后,出水苯酚去除率几乎为100%。The Ti/SnO2 plate electrode has been prepared by polymeric precursor process. The surface coatings form 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 ＆#183;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%.
