摘要

亚甲基蓝(MB)等工业染料造成的水污染因其高毒性和持久性而对环境构成重大挑战。本研究报告了利用硅藻土负载二氧化钛(TiO2)纳米颗粒对亚甲基蓝进行光降解的情况。使用傅立叶变换红外光谱(FTIR)、X 射线衍射(XRD)、拉曼光谱、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对样品进行了表征。利用紫外可见光谱测量了亚甲基蓝的光降解情况。结果表明,硅藻土的多孔结构与锐钛矿相和金红石相的光催化特性相结合,增强了亚甲基蓝的光降解过程,在自然阳光下 270 分钟内光降解效率达到 80%。这些发现凸显了硅藻土-二氧化钛复合材料作为一种低成本、有效的水净化和环境修复解决方案的潜力。

Diatomite with TiO2 nanoparticles for the photocatalytic degradation of methylene blue
Water pollution caused by industrial dyes, such as methylene blue (MB), poses a significant environmental challenge due to its high toxicity and persistence. This study reports the photodegradation of methylene blue using diatomite loaded with titanium dioxide (TiO2) nanoparticles. The samples were characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photodegradation of methylene blue was measured using ultraviolet–visible spectroscopy. The results indicate that the porous structure of diatomite, combined with the photocatalytic properties of the anatase and rutile phases, enhances the photodegradation process of Methylene blue, achieving an efficiency of 80% in 270 min under natural sunlight. These findings highlight the potential of the diatomite-TiO2 composite as a low-cost and effective solution for water purification and environmental remediation.
