Titanium dioxide (TiO) photocatalytic technology has the advantages of high catalytic activity, high chemical stability, nontoxicity, and low cost. Therefore, it finds widespread applications in the degradation of organic pollutants in water, antibacterial, environmental purification, and other fields. In this study, we have obtained a photocatalyst by modifying nanoTiO with the photosensitizer thioxanthone. The light-harvesting units of thioxanthone and nanoTiO can work synergistically to capture light energy. As a heterogeneous photocatalytic material, it can efficiently degrade organic dyes such as Rhodamine B, methyl blue and methyl orange. Specifically, the degradation rate of 0.1 mmol/L Rhodamine B can reach 97% after 35 min of irradiation, and methyl blue and methyl orange can also reach 98 and 56%, respectively.
二氧化钛（TiO）光催化技术具有催化活性高、化学稳定性高、无毒、成本低等优点。因此，它在水中有机污染物降解、抗菌、环境净化等领域有着广泛的应用。在本研究中，我们通过用光敏剂噻吨酮对纳米TiO进行改性，得到了一种光催化剂。噻吨酮和纳米TiO的光捕获单元可以协同工作以捕获光能。作为一种多相光催化材料，它可以高效降解罗丹明B、甲基蓝和甲基橙等有机染料。具体而言，0.1 mmol/L罗丹明B在光照35分钟后的降解率可达97%，甲基蓝和甲基橙的降解率也分别可达98%和56%。
