采用溶胶-凝胶法合成了掺镥二氧化钛（Lu-TiO2）。通过X射线衍射和电子顺磁共振对所得化合物进行了表征。研究了紫外线照射下 5'-三磷酸腺苷 (ATP) 的光催化分解，以评估掺杂镥的效果。我们的结果表明，Lu-TiO2 纳米颗粒比未掺杂的 TiO2 具有更高的光活性。此外，还讨论了镥在Lu-TiO2中的作用、Lu-TiO2光反应位点的结构以及反应机理。
Lutetium-doped titanium dioxide (Lu-TiO2) was synthesized using a sol–gel method. The obtained compounds were characterized by X-ray diffraction and electron paramagnetic resonance. The photocatalytic decomposition of adenosine 5′-triphosphate (ATP) under UV irradiation was investigated to estimate the effect of the doped lutetium. Our results showed that the Lu-TiO2nanoparticles have higher photoactivity than an undoped TiO2. Furthermore, the role of lutetium in Lu-TiO2, the structure of the photoreaction site on Lu-TiO2and the reaction mechanism are also discussed.
