Novel ZnIn2S4/FeUiO-66 (ZFeU) photocatalyst with different proportion of FeUiO-66 has been successfully prepared by a facile one-pot solvothermal reaction. The as-synthesized nanocomposites have been thoroughly characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform-infrared spectroscopy (FT-IR), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS), Brunauer–Emmett–Teller (BET) characterization, photoluminescence (PL) analysis and electrochemical impedance spectrum (EIS). The photocatalytic performance of ZFeU nanocomposites for the photodegradation of RhB under visible light irradiation was better than that of ZnIn2S4 and FeUiO-66 alone. The experiment results showed the 20% ZFeU nanocomposites had the best photocatalytic properties. At the same time, a probable mechanism was discussed and it was believed that introduction of FeUiO-66 on ZnIn2S4 would minimize the recombination of photogenerated electron-hole pairs, leading to the enhancement of the photocatalytic activity.

Fe掺杂UiO-66与ZnIn2S4结合在可见光下吸附降解RhB

新型锌2小号4/FeUiO-66（ZFeU）光催化剂通过简单的一锅溶剂热反应成功制备了不同比例的FeUiO-66。合成后的纳米复合材料已通过 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、傅里叶变换红外光谱 (FT-IR)、UV-Vis 漫反射光谱 (UV-Vis DRS)、Brunauer 进行了全面表征–Emmett–Teller (BET) 表征、光致发光 (PL) 分析和电化学阻抗谱 (EIS)。ZFeU纳米复合材料在可见光照射下光催化降解RhB的性能优于ZnIn2小号4和 FeUiO-66 单独。实验结果表明20%的ZFeU纳米复合材料具有最好的光催化性能。同时，讨论了一种可能的机理，认为在 ZnIn 上引入 FeUiO-662小号4将最大限度地减少光生电子 - 空穴对的复合，从而提高光催化活性。
