摘要
以对苯二酸作为Pt/TiO2光催化反应所产生的羟基自由基(?OH)的捕获剂,采用荧光技术考察外加磁场对羟基自由基(?OH)生成速率的影响,结果表明,与常规的光催化反应相比,外加磁场可使样品表面羟基自由基的生成速率提高11.7%.
The fluorescence technology was applied to study of the magnetic field effect on the rate of hydroxyl radical ·OH formation produced on the surface of Pt/TiO2 film in aerated NaOH solution, using terephthalic acid as the hydroxyl radical capturer. Compared with the normal photocatalytic reaction, the results showed that in the presence of external magnetic field the formation rate of surface hydroxyl radical was increased by 11.7%.
