Synthesis,Structure and Catalytic Properties ofβ-Octamolybdate Modified by Organic Copper

以三氧化钼、铜盐以及咪唑为主要原料,采用中温水热合成法制备出由有机铜修饰的八钼酸铵晶体材料.通过红外光谱、元素分析等方法确定该晶体材料结构为B型β构型的八钼酸铵衍生物,进一步进行环辛烯环氧化催化反应,发现该晶体材料的活性较好,有潜力成为性能优良的多相催化剂.

Crystal material of octamolybdate derivative was prepared by molybdenum trioxide,copper salts and imidazole under hydrothermal method. The structure of this material was characterized by IR spectrum,elemental analysis and X-ray diffraction. Determining the structure of crystal materil was B-type β-octamolybdate. And the catalytic performance by cyclooctene epoxidation catalysis reaction was tested. It was found that the reaction activity of the crystalline material was excellent. It proved this crystal material has potential to become a excellent performance heterogeneous catalyst.
