Abstract
In this work, the mixed-metal metal-organic frameworks MIL(Ti-Fe) were synthesized by the hydrothermal method. MIL(Ti-Fe) hybrid material was fabricated from ilmenite ore and 1,3,5-benzene tricarboxylic acid at a temperature of 130 oC for 24 hours. The prepared material was characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectroscopy (IR), and Brunauer-Emmett-Teller (BET) surface area. The obtained MIL(Ti-Fe) particles have a diameter of from 0.2-1.0 µm with a BET surface area of 85.482 m2 g-1. The influence of various vital parameters such as pH of the dye solution, initial dye concentration, adsorption time, and amount of the catalyst on the dye removal efficiency was investigated. The photocatalytic degradation rate of Rhodamine B was found to be 0.0074 min-1 at pH 7. The maximum removal of Rhodamine B was obtained at the catalyst dose of 1.0 g L-1. Under simulated sunlight irradiation, the resultant mixed-metals MOFs showed high photodegradation toward Rhodamine with degradation efficiency of approximately 99,97% after 6 hours. Furthermore, the resultant materials also showed remarkable absorption behavior toward Rhodamine B with the adsorption capacity of 70 mg g-1.
