| Popis: |
The preparation of SBA-15 materials involves both, calcination and activation processes. The effects of the temperatures of these stages on the silanol superficial concentration are studied experimentally. The characterization techniques employed were: nitrogen adsorption, infrared spectroscopy, nuclear magnetic resonance, and X-ray diffraction. To improve the concentration of silanols groups on the solid surface, the obtained results indicate that the best temperatures of calcination and activation are 623K and 373K, respectively. |
