Effect of the particle size and surface area of tungstated zirconia on the WOx nuclearity and n-heptane isomerization over Pt/WO3?ZrO2
Original language description
Four series of tungstated zirconia of different surface area ranging from 100 to 20 m2 g1 and of micro- and nano-meter crystal size were investigated with respect to nuclearity and reducibility of WOx species, concentration of strong and weak acid sites,and n-heptane isomerization over Pt/WO3?ZrO2. The nuclearity of WOx species was analyzed by diffuse reflectance UV?Vis spectroscopy and their reducibility by TPR-H2. TPD of ammonia distinguished acid sites of different strengths. n-Heptane isomerizationproceeds over Pt/WO3?ZrO2 in hydrogen/nitrogen mixture at 250 °C. At least four types of WOx species differing in nuclearity were identified in tungstated zirconia by a maxima of absorption at 39 000, 35 000, 30 000 and 27 000 cm1, intensity of which depended on the surface area, crystal size and WO3 loading.
