One-pot synthesis of Ag-Fe_3O_4 nanocomposite: a magnetically recyclable and efficient catalyst for epoxidation of styrene

摘要

With the assistance of PVP, a novel magnetically recyclable Ag-based catalyst has been synthesized in one pot, and it is found that this catalyst is highly efficient in selectively catalyzing styrene conversion to styrene oxide.rnHeterogeneous catalysts play key roles in liquid-phase catalytic processes that are important in the fine and speciality chemicals industry. It has been extensively demonstrated that nanometre-sized catalysts exhibit much higher activities than their bulk counterparts.
