The catalysts were characterized by means of TEM, XRD, N2 adsorption, and 1H MAS NMR. Brønsted type acidities of sulfated zirconia included SBA-15 materials were identified by a sharp 1H MAS NMR line at 10.6ppm. The highest acidity was obtained in the 25mol% ZrO2 included SBA-15 catalyst with a BET surface area of 246m2/g.
