通过低过饱和共沉淀方法合成了含铜锰的三元水滑石,并且对其进行了XRD,FT-IR和TG表征.XRD结果表明所合成的样品具有类似水滑石的层状结构.FT-IR红外表征结果表明所合成的样品具有相似的结构及表面吸附性质,而且样品的水滑石结构随着晶化时间的延长而变得更加完整,TG表征也显示了相同结果.实验表明:锰的加入和水滑石的特有晶体结构是苯甲醇无溶剂催化氧化的两个必要条件. The Cu-Mn-containing ternary hydrotalcites were synthesized by low-supersaturation coprecipitation method and characterized by XRD, FT-IR and TG.The XRD results showed that the synthesized samples had layered structure similar to hydrotalcite.The FT- IR results show that the synthesized samples have similar structure and surface adsorption properties, and the hydrotalcite structure of the sample becomes more complete with the extension of crystallization time, and the TG results also show the same result. The results show that the content of manganese The unique crystal structure of hydrotalcite and hydrotalcite are two necessary conditions for solvent-free catalytic oxidation of benzyl alcohol.
