Leaching features of Fe-MCM-41 during epoxidation of alkene with hydrogen peroxide
- 化学化工－已发表论文 
Fe-MCM-41 prepared by direct hydrothermal (DHT) synthesis is effective for epoxidation of alkenes with H2O2, and shows unique leaching behaviors. The Fe content remaining in the catalyst after reaction is 0.8 wt%, close to that capable of entering the framework of MCM-41. This value is almost independent of the Fe content in the fresh catalyst and is not changed after repeated reactions. The Fe cations in the framework are responsible for the epoxidation and stable towards leaching.
