| 摘 要： | 研究了N2/Ar介质阻挡放电处理对负载CuO的TiO2可见光光催化活性的影响.采用X射线衍射、紫外-可见分光吸收光谱、透射电镜、X射线光电子能谱和电子自旋共振进行了表征,详细考察了等离子改性参数包括气氛组成、处理时间和处理功率对改性效果的影响,并通过降解甲基橙溶液考察了可见光光催化活性.结果表明,最佳等离子处理条件为N2与Ar比例为8:2,处理时间为20 min,放电电流为1.0 A.最后,使用改性后的光催化剂对模拟含汞废水进行了处理.

| Abstract: | The effect of N2/Ar dielectric barrier discharge plasma on the photocatalytic activity of CuO/TiO2 under visible light irradiation was studied. The photocatalysts were characterized by X-ray diffraction, ultraviolet-visible spectrophotometry, transmission electron microscopy, X-ray photoelectron spectroscopy, and electron paramagnetic resonance spectroscopy. The plasma parameters including gas composition, treatment time, and plasma power were investigated. The activities of the plasma-treated photocatalysts were evaluated by the photodegradation of methyl orange under visible light illumination. The optimal operation conditions were N2:Ar = 8:2, treatment time of 20 min, and a discharge current of 1.0 A. Simulated mercury-containing wastewater was treated by the photocatalysts. |
