International audience; Cerium-containing oxide materials have several very interesting applications due to their capacity to store and release oxygen under oxidizing and reducing conditions respectively. In the case of pure ceria this property is hi

1.1 wt% Cu and 1 wt% Au/CeO 2 catalysts were prepared by impregnation of a high-surface area ceria (>200 m 2 g −1 ) with copper nitrate and dimethyl(acetylacetonate) gold(III), respectively. They were dried and calcined in air at 300 °C. They were

Platinum catalysts supported on zeolite KY (Si/Al = 12.7), modified with magnesium, calcium or barium, were evaluated in n-octane reforming to produce ethylbenzene. The catalysts were characterized by nitrogen adsorption, 27Al and 29Si solid state nu
