Abstract: 4N-TiO2 particles and MIL-125 were prepared by the sol-gel method and hydrothermal method respectively.The MIL-125/4N-TiO2 were prepared by coordination reaction induced self-assembly route.The MIL-125/4N-TiO2 was characterized by scanning electron microscope (SEM),infrared spectroscopy (IR),X-ray diffraction (XRD) and nitrogen adsorption-desorption isotherm.Based on the results,it was found that MIL-125/4N-TiO2 was synthesized successfully.Through the photocatalytic degradation of rhodamine 6G model compounds,the composite had the property of photocatalytic degradation.When pH value was 7,the ratio of MIL-125 and 4N-TiO2 was 1∶1,the degradation ratio was the best of 98.12%.When the ratio of MIL-125 to 4N-TiO2 was 3∶1,the adsorption ratio was 63.7%.By comparing the infrared spectra of composites before and after photocatalytic oxidation,it was concluded that the composite was able to adsorb rhodamine 6G,and then photocatalytic degraded it.
