Abstract

MOFs has the characteristics of higher specific surface area,higher porosity,adjustable structure and functionability.In recent years,metal organic framework (MOF) composites have developed rapidly as new functional materials,and the application of MOFs-based composites in catalytic degradation of organic pollutants in water has become an important research direction.Terephthalic acid and 2-methyl-imidazole were added to the mixed solution of N,N-dimethyl-formamide and methanol,and then Zn(NO3)2·6H2O was added to the above mixed solution,and the double ligand Zn-MOF was synthesized at 150 degrees,and Pd was supported on double ligand Zn-MOF by sodium borohydride reduction to obtain uniformly dispersed Pd@Zn-MOF.By means of field emission scanning electron microscope (SEM),field emission transmission electron microscope (TEM),X-ray diffractometer (XRD) and other testing methods,the morphology,structure and composition of Pd@ Zn-MOF material samples were characterized.The catalytic degradation performance of Pd@Zn-MOF was observed by UV-visible spectrophotometer (UV-Vis) with the reduction reaction of methylene blue and sodium borohydride as a model.
