中文摘要：

以钛酸丁酯为前驱体、无水乙醇为溶剂，采用溶胶-凝胶法和浸渍法制备了不同Ce、Nd掺杂量的TiO2／C复合材料光催化剂．通过X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT—IR）、固体粉末紫外漫反射等对样品进行了表征，并在紫外光照射下，以亚甲基蓝（MB）为降解物，研究了不同Ce、Nd含量样品的光催化性能．

英文摘要：

TiO2/C composite material photocatalysts co-doped with different contents of Ce and Nd were prepared with sol-gel method and impregnation method, with tetrabutyl titanate as precursor and ethanol as solvent. Samples were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, fourier transform infrared spectroscopy （FT-IR）, and solid powder UV diffuse reflection. Under UV irradiation, with the methylene blue （MB） as a degradation product, the photocatalytic performances of samples with different contents of Ce and Nd were researched.
