Synthesis and Characterization of Bimetallic Ag-Mn-MCM-41 Materials

The series of mesoporous, bimetallic Ag-Mn-MCM-41 materials were synthesized by applying direct synthesis and ion-exchange methods. Their surface and structure characteristics were analyzed using nitrogen adsorption/desorption isotherms, XRD data, FT-IR/PA spectrometry, and temperature programmed reduction. The differences between the porous structure and the forms of metallic species formed in the structure and on the silica surface were found for the materials synthesized by direct synthesis and ion-exchange method.
