采用浸渍法制备了负载催化剂MCM-41包裹Fe3O4负载乙酰丙酮铜[Fe3O4@MCM-41/Cu（acac）2],利用红外光谱（IR）和X-射线粉末衍射（XRD）对负载催化剂的结构进行了表征,并采用原子吸收光谱（AAS）测定了负载催化剂中的Cu负载量;研究了负载催化剂在二氧化碳（CO2）和氧化苯乙烯（SO）偶联合成苯乙烯环状碳酸酯（SC）反应中的催化性能,考察了Cu负载量、反应温度、反应压力和反应时间等对SC合成的影响,并采用气相色谱（GC）对SC产率进行了定量分析,利用磁铁对负载催化剂进行了回收并研究了其循环催化性能。结果表明,负载催化剂具有较高的催化活性,SC产率高达91.7%;在重复使用5次后,负载催化剂的催化活...

Supported catalyst Fe3 O4 @MCM-41/Cu(acac)2 was prepared by an impregnating method.The structure of the supported catalyst was characterized by infrared spectroscopy(IR)and X-ray powder diffraction (XRD),and Cu loading amount of the supported catalyst was determined by atomic absorption spectroscopy (AAS).The catalytic performance of the supported catalyst for the synthesis of styrene carbonate(SC)from carbon dioxide(CO2 )and styrene oxide(SO)was investigated.The reaction conditions including Cu loading a-mount,reaction temperature,reaction pressure and reaction time were optimized,and the yie...
