通过直接自组装的方法制备了Fe3O4 NPs@MIL-53复合材料,并且通过PXRD,FTIR,TEM以及77 K下的N2吸附进行了表征。结果显示Fe3O4 NPs是被嵌入到MIL-53骨架结构中并被固定在晶格内部。Fe3O4 NPs@MIL-53复合材料对苯乙烯催化环氧化有高的选择性。PRXD证明了Fe3O4 NPs@MIL-53复合材料的酸稳定性。
The Fe3O4 NPs@MIL-53 composite has been prepared by method of directing self-assembly (DSA) and characterized by PXRD, FTIR, TEM and N2 adsorption at 77 K. The results show that Fe3O4 NPs are embedded into the framework of MIL-53 and locked inside by the lattice of MIL-53. The catalytic performance exhibits that Fe3O4 NPs@MIL-53 composite can selectively catalyze the styrene epoxidation. PXRD testifies the acidic stability of Fe3O4 NPs@MIL-53 composite.
