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 …

Quantitative IR studies of the concentration of Co2+ and Co3+ sites in zeolit…
Abstract Quantitative IR experiments were realized to determine the concentration of cobalt in a form of trivalent cations being in the oxide form as well as divalent ions in exchange positions, oxide-like clusters and cobalt oxide, present in a series of cobalt-exchanged zeolites. The first step of such quantitative studies was to elaborate the experimental conditions in which probe molecu…
