Özet:

 

Mesoporous Ba/MCM-41 type materials (Ba/MCM-41) with high  Ba/Si molar ratios between 0.025 and 0.1 were synthesized by direct  hydrothermal synthesis.  The samples were characterized by XRD,  nitrogen adsorption, TGA-DTA, FTIR, SEM-EDS, and TEM techniques.  BET  surface areas of samples with various Ba loadings were found between  722 and 931 m2/g with 28 Å average pore size, which is consistent  with the pore size of 30 Å for pure MCM-41 samples synthesized by the  same procedure.  The crystal structures of synthesized MCM-41 and  Ba/MCM-41 were confirmed by XRD analysis.  Among the investigated  Ba/MCM-41 samples, the formation of barium oxide and barium nitrate  species besides silicates was also observed in the high angle region  XRD patterns.
