and it was used as a capping agent during the synthesis of Fe3O4 NPs. The resulting modified quinidine capped Fe3O4 (Fe3O4@mQD) NPs were characterized by different techniques and used for enantioselective ring opening (ERO) by methanolysis in a heterogeneous mode of catalysis. The interactions of mQD with the Fe3O4 surface, as well as its % loading, were studied using FTIR spectroscopy and thermal analysis
在目前的工作中,
