Efecto de la temperatura de calcinación sobre la concentración de grupos silanoles en superficies de SiO2 (SBA–15)
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, n...
