纳米二氧化钛薄膜协同接触辉光放电技术降解亚甲基蓝

Degradation of methylene blue by coupling system of nano-TiO_2 film and contact glow discharge electrolysis

通过溶胶-凝胶法制得纳米TiO_2薄膜,研究了日光条件下亚甲基蓝在薄膜上的光催化降解以及在TiO_2协同接触辉光放电条件下的降解,结果表明:镀膜5次所得薄膜具有高的催化性能;TiO_2协同接触辉光放电可以高效地降解亚甲基蓝分子;所制得的薄膜随使用次数的增加而活性变化不大。

TiO2 was immobilized on glass by using sol - gel method, the degradation of methylene blue by coupling system of TiO2 film and contact glow discharge electrolysis was studied. The results showed that the TiO2 film with 5 layers has high catalytic activity. Using the coupling system can degrade the molecule of methylene blue more efficiently and the prepared TiO2 film has a good durability.
