Polyoxometalate-based amino-functionalized ionic solid catalysts lead to highly efficient heterogeneous epoxidation of alkenes with H2O2

摘要

Polyoxometalate(POM)-based ionic hybrid nanospheres prepared by protonating and anion-exchanging amino-attached ionic liquid cations with Keggin POM-anions have proven to be highly efficient heterogeneous catalysts for the epoxidation of alkenes with H2O2, presenting advantages of convenient recovery, steady reuse, simple preparation, and flexible composition.
