The materials prepared by grinding method are characterized by X-ray diffraction, infrared spectrum analysis, and N2 adsorption and desorption.
DNA extractions were performed by the liquid nitrogen grinding method as previously described [9].
The MCM-41/CeO2 and MCM-48/CeO2 prepared by grinding method showed the higher photoreactivity with 97.6 % and 93.1 %, respectively, of degradation of Congo red.
Among the prepared catalysts, the mesoporous MCM-41/CeO2 and MCM-48/CeO2 that were synthesized by grinding method show the most photocatalytic activity with 97.6 % and 91.3 % photodegradation of CR, respectively.
Apparently, the most cerium ions are doped in mesoporous materials by grinding method, and the weight percentage of CeO2 in MCM/CeO2 is near 40%% which is in accordance to what was mentioned in the 'Methods' section.
The Fe-MCM-48 was prepared by a grinding method as a solvent-free procedure.
MCM-41/CeO2 and MCM-48/CeO2 were synthesized by direct and indirect methods in solvent media and by grinding method in a solvent-free media.
The characterization of MCM-41, MCM-48, MCM-41/CeO2, and MCM-48/CeO2 prepared by grinding method are performed using X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and Brunauer, Emmett, and Teller (BET) N2 adsorption-desorption isotherm.
In addition, particle size distribution (PSD) and long term properties of blended cements with same percentage of 45-μm residue were not affected significantly by grinding method.
Finally, it was concluded that physical properties of cements obtained by Inter-grinding were slightly better than that of separate grinding; however, durability properties were not affected by grinding method.
