【摘要】 制备二氧化钛（TiO₂）光阳极材料，通过表征手段考察其形貌、晶相与元素组成特征。TiO₂纳米棒形成纳米管阵列，在XRD图谱27.5°、36.1°、37.8°和62.7°处有明显特征峰，无明显杂峰，Ti元素以Ti⁴⁺的形式存在。选取一种喹诺酮类抗生素恩诺沙星（ENR）作为目标污染物，探究光-电催化体系下TiO₂光阳极材料对ENR降解的影响因素。实验结果表明，ENR初始浓度为10 mg/L，电解质NaCl浓度为0.10 mol/L，外加偏压为1.2 V，初始pH值为7时，TiO₂光阳极材料对ENR的光-电催化降解率可达90.74%，经四次循环实验材料保持了良好的稳定性，在抗生素降解方面具有较大的应用潜力。更多还原

【Abstract】 We prepared Titanium dioxide （TiO₂） photoanode,and investigated its morphology,crystal phase,and element composition by characterization means.TiO₂ nanorods form nanotube arrays with distinct characteristic peaks at 27.5°,36.1°,37.8°,and 62.7°of the XRD pattern,without obvious hybrid peaks.Ti element exists in the form of Ti⁴⁺.A quinolone antibiotic enrofloxacin （ENR） was selected as the target pollutant to explore the influence factors of Ti O₂ photoanode material on ENR degradation in the photoelectrocatalytic system.The experimental results showed that the photoelectrocatalytic degradation efficiency of TiO₂ photoanode could reach 90.74% when the initial concentration of ENR was 10 mg/L,the concentration of NaCl was 0.10 mol/L,the applied bias voltage was 1.2 V,and the initial pH value was 7.TiO₂ photoanode maintained good stability after four recycling experiments and it exhibits great application potential in antibiotics degradation.更多还原
