Abstract:

Metal-organic framework materials are composite materials composed of inorganic metal ions and organic ligands, which have high metal dispersion and catalytic activity. In this paper, an organic framework material Mo-MOF was synthesized using molybdic acid as molybdenum source and terephthalic acid as ligand by static mixed solvothermal crystallization method. The morphology, structure and composition of the materials were characterized by X-ray diffraction(XRD), Fourier exchange infrared spectroscopy(FTIR), scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). Mo-MOF catalysts synthesized by static mixed solvothermal method (water and ethanol) showed the best catalytic activity, with 100% conversion of conversion of diphenylthioether and 86.4% selectivity of diphenylsulfoxide in the selective oxidation using oxygen without other additives.

Key words: Mo-MOF, Thioether, Oxygen, Selective oxidation, Sulphoxide
