纳米球型 Mo-MOF 材料的调控合成及催化硫醚选择性氧化

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.
