Abstract In the present study, we explored the effective and enhanced photocatalytic degradation of diclofenac (DF) using Ce@TiO2 nanocomposites. The Ce@TiO2 nanocomposites was synthesized by simple precipitation method and characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and diffuse reflectance spectroscopy (DRS). The photocatalytic degradation of DF solution was investigated in the presence of Ce@TiO2 nanocomposites under UV irradiation. The extensive analysis of stability and reusability were investigated with photocatalytic degradation of DF, rose Bengal (RB) and acid red (AR). The catalyst was stable up to 6th run. The present investigation may be much useful for the application of Ce@TiO2 nanocomposite in wastewater treatment.

Ce@TiO 2 纳米复合材料：一种用于光降解双氯芬酸钠的高效、稳定且价格合理的光催化剂

摘要 在本研究中，我们探索了使用 Ce@TiO2 纳米复合材料对双氯芬酸 (DF) 的有效和增强的光催化降解。Ce@TiO2纳米复合材料通过简单的沉淀法合成，并通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、光致发光（PL）和漫反射光谱（DRS）表征。在紫外光照射下，研究了在 Ce@TiO2 纳米复合材料存在下对 DF 溶液的光催化降解。用光催化降解 DF、玫瑰红 (RB) 和酸性红 (AR) 研究了稳定性和可重复使用性的广泛分析。催化剂稳定到第 6 次运行。目前的研究可能对 Ce@TiO2 纳米复合材料在废水处理中的应用非常有用。
