A simple and facile solvothermal method is developed for the preparation of a reduced graphene oxide/NH₂-MIL-125(Ti) (rGO–NMTi) hybrid nanocomposite photocatalyst with large specific surface area and thermal stability. This rGO–NMTi-x hybrid nanocomposite exhibited a more efficient photocatalytic performance than NH₂-MIL-125(Ti) for methyl blue (MB) degradation under visible-light irradiation due to the synergetic action between rGO and NH₂-MIL-125(Ti). Therefore, rGO/MOFs photocatalysts have great potentiality in environmental remediation. The structure and physical properties of rGO, NH₂-MIL-125(Ti) and rGO–NMTi-x hybrid nanocomposites were characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), N₂ adsorption/desorption, high resolution transmission electron microscopy (HRTEM), laser Raman, UV-visible absorption spectra (UV-DRS) and FT-IR techniques.

新型稳定的还原氧化石墨烯/ MOF杂化纳米复合材料的合成及光催化降解染料的性能

开发了一种简单易行的溶剂热方法，用于制备具有较大比表面积和热稳定性的还原型氧化石墨烯/ NH ₂ -MIL-125（Ti）（rGO-NMTi）杂化纳米复合光催化剂。这种rGO-NMTi- x杂化纳米复合材料在可见光照射下对甲基蓝（MB）的降解表现出比NH ₂ -MIL-125（Ti）更有效的光催化性能，这是由于rGO与NH ₂ -MIL-125之间的协同作用。（钛）。因此，rGO / MOFs光催化剂在环境修复方面具有很大的潜力。rGO ，NH ₂ -MIL-125（Ti）和rGO–NMTi- x的结构和物理性质通过扫描电子显微镜（SEM），X射线衍射（XRD），N ₂吸附/解吸，高分辨率透射电子显微镜（HRTEM），激光拉曼，紫外可见吸收光谱（UV-DRS）表征杂化纳米复合材料和FT-IR技术。
