摘要
通过液相沉积法在较低的温度下制备了TiO2/SiO2复合薄膜,利用UV Vis、XRD和SEM等表征手段对薄膜的透明性、物相和表面形貌进行了表征;并在紫外光照下,通过薄膜对罗丹明B水溶液的光催化降解实验,评价了沉积薄膜的光催化活性.实验结果表明,在室温下制备的液相沉积膜具有较好的光催化活性.
TiO_2/SiO_2 complex thin films were prepared by liquid phase deposition method at low-temperature.Their transparent,crystal structure and image were characterized by UV-Vis,XRD and SEM spectra,respectively.The evaluation of photocatalytic activities of deposited thin films were carried out by degradation of Rhodamine B in water solution under UV irradiation.The results exhibited that complex thin films prepared at room temperature have higher reactivitity for degradation of Rhodamine B.
