The adsorption of Rhodamine B in aqueous phase was studied by one-step crystallization method of metallic organic matrix supported TiO2/Cu-MOF catalyst using cupric nitrate trihydrate as copper source.The microstructure and surface properties of TiO2/Cu-MOF were characterized by N2 adsorption-desorption (BET),X-ray diffraction (XRD),scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS).The results shown that the catalyst had good catalytic degradation effect and cycling performance.TiO2/Cu-MOF catalyst (0.3g/L) and H2O2 (3.5mmol/L) were added at the initial concentration of 20mg/L rhodamine B under the condition of light pH=6,30℃,and stable for 120min.The decolorization rate of TiO2/Cu-MOF nanocomposite was 98.15%.Moreover,the decolorization rate of TiO2/Cu-MOF could still maintain high after 4 cycles.Finally,the degradation process of rhodamine B was analyzed,and the degradation mechanism was discussed.
