Cu-TiO2纳米薄膜制备及光催化降解染料废水性能
Preparation of Cu-TiO2 nanofilms and their performance in photocatalytic degradation of dye wastewater
摘要
Abstract
Anatase-phase Cu-doped TiO2(Cu-TiO2)modified nanofilms were successfully prepared via direct current(DC)magnetron sputtering.The doping concentration and modification degree and were precisely controlled by adjust-ing the Cu sputtering power.The microstructure,surface morphology,and optical properties of the nanofilms were sys-tematically characterized using ultraviolet-visible diffuse reflectance spectroscopy(UV-Vis DRS),atomic force micros-copy(AFM),and scanning electron microscopy(SEM).Photocatalytic degradation experiments under simulated natural light showed that the Cu-TiO2 nanofilm prepared at a Cu sputtering power of 9 W exhibited the optimal photocatalytic ac-tivity:for 15 mg/L methyl orange solution,the degradation rate reached 91.5%within 50 minutes,which was 45%high-er than that of undoped pure TiO2 nanofilms.The photocatalytic cycle stability test demonstrated that the catalyst re-mained effective after five cycles,maintaining a degradation rate of 87.6%within 50 minutes.In addition,the film-based catalyst also has the advantages of high stability,easy recovery,and high reusability,showing great application potential in the degradation of dye wastewater.关键词
