Acidity and catalytic activities of sulfated zirconia inside SBA-15

Abstract. SBA-15 containing various amount (10–50 wt.%) of highly dispersed ZrO2 is prepared using urea hydrolysis method. The sulfated zirconia (ZrO2) in SBA-15 catalysts were prepared using these materials. The materials were characterized by XRD, BET surface area, TEM, TGA, acidity measurements using in situ IR pyridine adsorption, sulfate content and catalytic activities were studied …
