本文以水热法制备的碳球为模板，制备了Gd掺杂的二氧化钛空心球。采用XRD、TEM、SEM、DRS和XPS等手段对样品进行了表征。以活性艳红X-3B（C.I.活性红2）在可见光照射下。研究了Gd掺杂量对TiO 2空心球的物理结构和光催化性能的影响。结果表明，Gd掺杂量存在一个最佳值（4%），对X-3B的光催化降解效果最好。
In this work, Gd-doped titania hollow spheres were prepared using hydrothermally prepared carbon spheres as template. The prepared samples were characterized by XRD, TEM, SEM, DRS and XPS. The photocatalytic activity of as-prepared hollow titania spheres was determined by degradation of Reactive Brilliant Red dye X-3B (C.I. reactive red 2) under visible light irradiation. The effect of Gd content on the physical structure and photocatalytic properties of doped titania hollow sphere samples was investigated. Results showed that there was an optimal Gd-doped content (4%) for the photocatalytic activity of X-3B degradation.
