	1	纳米Ce_1Mg_xZr_(1-x)O_2固体多相催化剂的制备、表征及催化合成四氢苯并[b]吡喃衍生物的性能(英文)显示文摘A series of Ce1MgxZr1-xO2 mixed metal oxides with different molar ratios were prepared by simple co-precipitation and were characterized by X-ray diffraction,infrared spectroscopy,scanning electron microscopy,energy dispersive spectroscopy,temperature-programmed desorption of CO2,and N2 adsorption techniques.The prepared materials were tested for catalytic activity by the synthesis of tetrahydrobenzo[b]pyran derivatives using a three component reaction(aromatic aldehydes,malononitrile,and dimedone) in an ethanol medium.The best catalytic activity was obtained with Ce1Mg0.6Zr0.4O2.The particle size or crystallite size was estimated using the Debye-Scherrer equation.The addition of magnesium oxide into the ceria-zirconia lattice resulted in the formation of nanosized particles ranging from 5.41 to 9.78 nm.This work describes the catalytic behavior of magnesium oxide in mixed metal oxide systems.
