Enhanced Degradation of Rhodamine B by Metallic Organic Frameworks Based on NH-MIL-125(Ti) under Visible Light.

Samples of the bimetallic-based NH-MIL-125(Ti) at a ratio of M/Ti is 0.15 (M: Ni, Co and Fe) were first synthesized using the solvothermal method. Their fundamental properties were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectra, scanning electron microscopy (SEM), N adsorption-desorption measurements, and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS).
