“…6, the Ce x Zr 1−x O 2 /SiO 2 composite catalyst shows excellent performance in the time-on-stream experiments revealing the stable catalytic activity without deactivation. Recent literature reveals that ceria-based mixed oxides, especially ceria-zirconia combinations are highly coke resistant and exhibit promising stable activity without deactivation during time-on-stream runs for various reactions [9][10][11]26]. This was mainly attributed to the availability of lattice oxygen due to oxygen storage and release property of the Ce-Zr-oxides [14,26].…”

“…Hence, ceria-zirconia solid solutions have been investigated with huge interest among other ceria-based mixed oxides [5][6][7]. Typical catalytic applications of these oxides include partial oxidation of methane to generate hydrogen for fuel cell applications [9], CO 2 reforming of methane to produce synthesis gas [10], direct oxidation of methane in the solid oxide fuel cells (SOFC) [11], steam reforming of ethanol [12] and hydrodesulfurization sorbents [13].…”

“…1 shows, schematically, the fluorite structure of ceria. The high level of interest is due to important industrial applications such as solid oxide fuel cells, insulators, high refractive index materials, UV blockers, polishing materials, gas sensors, high-temperatureoxidation resistance, free-radical scavengers…etc (see for example [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]). However, the most important applications of cerium oxide are as catalysts, catalyst promoters or catalyst supports, such as those used in automobile mufflers (three-way catalysts) and those related to toxic emission control (e.g.…”

“…This idea has been recently exploited at CINSO to develop high-performance cathodes [22]. Besides, in a previous work [23], we showed the excellent catalytic properties for CH 4 oxidation of nanocrystalline ZrO 2 -50 mol%, 70 mol% and 90 mol% CeO 2 solid solutions exhibiting the t -form of the tetragonal phase, the t -form of the tetragonal phase and the cubic phase, respectively. The synthesis of these nanocrystalline ZrO 2 -CeO 2 solid solutions by gel-combustion routes, their crystal structure and the retention of metastable forms of the tetragonal phase in these materials have also been subjects of intense investigation at CINSO [8,9,[24][25][26].…”
