采用共沉淀-水热法合成了一系列的类水滑石样品.用XRD、TEM等表征了合成样品的结构及表面形貌;用NH3-TPD、CO2-TPD测试样品表面酸碱性质,优化了镁铝水滑石的合成条件,重点考察了镁铝比对合成样品晶形的影响和样品表面酸碱性变化的规律,阐述了层板上原子配位分布的微观结构,以及不同镁铝比的类水滑石在催化丙酮缩合制备双丙酮醇反应中催化性能.
A series of hydrotalcite-like samples were synthesized by coprecipitation-hydrothermal method. The structure and surface morphology of the synthesized samples were characterized by XRD, TEM and so on. The surface acid-base properties of samples were tested by NH3-TPD and CO2-TPD Magnesium aluminum hydrotalcite synthesis conditions, focusing on magnesium and aluminum ratio on the synthesis of the sample shape and the sample surface acid-base changes in the law, elaborated on the distribution of the atomic distribution of the microstructure, as well as different types of magnesium and aluminum ratio Catalytic Performance of Hydrotalcite in the Synthesis of Diacetone Alcohol via Acetone Condensation.
