【摘要】 报道了用紫外分光光度法间接测定ＰｈｏｔｏＦｅｎｔｏｎ反应即利用光激发ＴｉＯ２超细颗粒产生的Ｈ２Ｏ２进行Ｆｅｎｔｏｎ反应．产生的羟自由基．通过对测定结果的分析，得到ＴｉＯ２超细颗粒与光激发ＴｉＯ２超细颗粒产生的羟自由基之间的定性和定量关系，从而为进一步研究纳米材料的光催化氧化机理提供一种简单易行的方法更多还原

【Abstract】 The Fenton reaction utilizing H 2O 2 formed on photoexcited TiO 2 particles, i.e., Photo Fenton type reaction, is performed successfully and the ·OH from the reaction is indirectly measured by UV spectrometer. We can conclude the qualitative and quantitative relationship between TiO 2 particles and ·OH from photoexcited TiO 2 particles. It provides a convenient way to make a thorough study on the mechanisms of semiconductor for photocatalysis.更多还原
