Nano Fe-BTC/graphene oxide (GO) composites were successfully synthesized by hydrothermal treatment with a microwave-assisted method. Samples were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), N₂ adsorption–desorption, Scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS), and Ultraviolet–visible diffuse reflection spectroscopy (UV–Vis DRS). SEM image of Fe-BTC/GO-30 showed the particle size of 30–50 nm on the GO surface. From the UV–Vis diffuse reflectance spectra, it revealed that nano Fe-BTC/GO composite absorbed the wavelengths in the visible light region with a low bandgap energy of 2.2–2.45 eV. Fe-BTC/GO nanocomposites were tested for the photocatalytic degradation of reactive yellow 145 (RY-145) in aqueous solution. Fe-BTC/GO composites exhibited high photocatalytic activity. Thus, at pH of 3 and high initial concentration of 100 mg RY-145/L, removal efficiency reached the value of 98.18% after 60 min. of reaction. In comparison with Fe-BTC/GO synthesized by the solvothermal method, nano Fe-BTC/GO showed much higher RY-145 removal efficiency. Moreover, this Fe-BTC/GO-30 showed high catalytic activity stability and could be reused, opening the high potential application of this promising photo-Fenton catalyst in photocatalytic degradation of organic pollutants from aqueous solution.

通过微波辅助水热处理成功合成了纳米Fe-BTC /氧化石墨烯（GO）复合材料。通过X射线衍射（XRD），傅立叶变换红外光谱（FTIR），N ₂表征样品吸附-解吸，扫描电子显微镜（SEM），能量色散X射线光谱（EDS）和紫外-可见漫反射光谱（UV-Vis DRS）。Fe-BTC / GO-30的SEM图像显示GO表面的粒径为30–50 nm。从UV-Vis漫反射光谱中可以看出，纳米Fe-BTC / GO复合材料以2.2-2.45 eV的低带隙能量吸收了可见光区域的波长。测试了Fe-BTC / GO纳米复合材料在水溶液中对活性黄145（RY-145）的光催化降解。Fe-BTC / GO复合材料表现出很高的光催化活性。因此，在3的pH值和100 mg RY-145 / L的高初始浓度下，去除效率在60分钟后达到98.18％。反应。与溶剂热法合成的Fe-BTC / GO相比，纳米Fe-BTC / GO显示出更高的RY-145去除效率。而且，该Fe-BTC / GO-30具有高催化活性稳定性，可以重复使用，从而开启了该有希望的光芬顿催化剂在光催化降解水溶液中有机污染物方面的巨大潜力。
