摘　　要：以过渡元素Co为一取代原子合成Keggin结构杂多钨硅酸盐异构体,在水热条件下与十二烷基三甲基溴化铵进行化合,得到4种新的基于Keggin型多酸阴离子和有机物的复合材料。通过FT-IR、TG、XRD、SEM等手段进行结构表征,并采用抑菌圈法对大肠杆菌进行抑菌活性研究。结果表明,所合成的复合材料的分解温度较季铵盐升高了160℃,复合材料的抑菌效果是季铵盐的2～3倍。Using the transition element Co as mono-substituted atom, the heteropotytung stosilicate isomers with the Keggin structure were synthesized. Then combining with the dodecyl trimethyl ammonium bromide, under the hydrothermal conditions, four kinds of new polyoxometalate and organic composite materials with Keggin structure were obtained. The structures were characterized by FI＇-IR, TG, XRD and SEM, and the colibacillus were employed to detect the antibacterial activities of these compounds, using the inhibition zone method. The experimental results show that, the decomposition temperature of these composite materials are 160 ℃higher than quaternary ammonium salts, and the antibacterial activity is 2--3 times of them.
