【摘要】 利用阳极氧化法在纯钛片表面制备了TiO2纳米管阵列膜和TiO2多孔膜,采用场发射扫描电镜(FESEM)和XRD对制备的两种膜的形貌和晶体结构进行表征。以10mg/L的甲基橙溶液为降解物进行光催化试验,研究了TiO2纳米管阵列膜TiO2多孔膜的光催化效果。结果表明,TiO2纳米管阵列的光催化降解能力比TiO2多孔膜高69%,锐钛矿型的TiO2纳米管阵列膜光催化效果最好。更多还原

【Abstract】 TiO₂ nanotube arrays film and TiO₂ porous film are prepared in the surface of pure titanium sheet by anodic oxidation method. The morphology and the crystal structure of the TiO₂ nanotube arrays film and TiO₂ porous film are analyzed by field emission electron microscope （FESEM） and XRD. In photocatalysis experiment, methyl orange （ 10mg/L ）was used as the degraded agent. The result indicates the photocatalysis property of TiO₂ nanotube arrays film is 69% higher than TiO₂ porous film. Anatase TiO₂ nanotube arrays film has the best photocatalysis.更多还原
