摘要:

金属有机骨架材料是一种由无机金属离子和有机配体配位组成的复合材料, 拥有较高的金属分散度和催化活性. 本文采用静态混合溶剂热晶化法, 以钼酸为钼源、 对苯二甲酸为配体合成了有机骨架材料 Mo-MOF. 通过X射线衍射(XRD)、 傅里叶变换红外光谱(FTIR)、 扫描电子显微镜(SEM)和X射线光电子能谱(XPS)等手段表征了催化剂的形貌、 结构和组成. 采用静态混合溶剂热法(水和乙醇)合成的Mo-MOF催化剂表现出最佳的催化活性, 在未加其它助剂的条件下实现二苯基硫醚与氧气的选择性氧化, 并可以得到100%的转化率和86.4%的二苯基亚砜的选择性.

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
