摘要
采用sol-gel法制备TiO2薄膜光电极,以该电极为工作电极,铂丝作对电极,饱和甘汞电极为参比电极,对壬基酚的光电催化降解进行了研究。结果表明:该电极具有n型半导体的特征行为。在外加偏压为+0.8V、pH=5、、30mg/L的H2O2中对初始浓度为20mg/L的壬基酚溶液光照180min降解率达62.22%。讨论了氧的存在、外加偏压、pH等因素对光电催化反应的影响。
A three-electrode system composed of TiO2/Ti prepared by sol-gel method as working electrode, Pt wire as counter electrode and saturated calomel electrode as reference electrode was used for photoelectrocatatlytic degradation of nonylphenol, one of endocrine disrupting chemicals. Results showed that rate of photodegradation of nonylphenol reached 62.22% under condition of pH of 5, H2O2 of 30mg/L, external potential +0.8v and 180min irradiation.
