Intercalation catalysts , owing to their modular and accessible gallery and unique interlamellar chemical environment, have shown a wide range of applications in various catalytic reactions. However, the poor mass‐transfer between the active components of the intercalated catalysts and organic substrates is one of the challenges that limit their further applications. A novel heterogeneous catalyst was fabricated by intercalating the active polyoxometalate (POM) into the ionic‐liquid‐modified layered double hydroxides (LDHs). This novel intercalation catalyst demonstrates high activity and selectivity for epoxidation of various allylic alcohols in the presence of H 2 O 2 under mild conditions.
