Features of a Hybrid Mn(II)-Modified Mesoporous MCM-41 Material

Abstract

The synthesis of hybrid Mn(II)-modified mesoporous MCM-41 material has been carried out. In this work, mesoporous MCM-41 was heated at 200oC for 3 hours and then modified through reacting with aniline and boron trifluoride at room temperature. The modified mesoporous MCM-41 was Hybridized with Mn(II) ion by a process reflux in acetonitrile solvent for 2 hours at 60oC. The obtained material was characterized by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and Atomic Absorption Spectroscopy (AAS). FTIR analysis showed that Mn(II) ion was incorporated into the modified mesoporous MCM-41. The morphology of Mn(II)-modified mesoporous MCM-41 was examined by SEM. From the SEM images it can be seen that the aggregates of MCM-41 break after being modified with the boron compound and manganese (II). Based on measurement of metal content by AAS, it was known that the value of metal loading is 67.60%. While for the leaching test, the hybrid material disappeared only 0.006% of Mn(II) ion which proved the stability of the interaction between Mn(II) ion and modified mesoporous MCM-41. Accordingly, this material is of the great interest for catalytic applications.
