Activity of Cu-Co-M (M= Ce, Ni, Au, Mg) catalysts prepared by coprecipitation method, calcined at high temperature for CO oxidation
The present study deals with analysis of the activity of catalysts prepared by addition of different metals to Copper and Cobalt based catalysts for CO oxidation and the variation in activity caused by changes in composition. A series of catalysts were prepared with Cu:Co molar ratio 1:4 and a third metal (M= Ce, Ni, Au, Mg) was added in three different quantities. Compositions were prepared by...

متن کاملSynthesis of La1-xSrxAlO3 Perovskites by Reverse Strike Co-Precipitation Method and Its Soot Oxidation Activity
La1-xSrxAlO3 (x=0 to 0.4) perovskite materials were synthesized by the reverse strike co-precipitation method and their soot oxidation activity was evaluated. All the catalysts synthesized were characterized using XRD, BET specific surface area, FESEM and XPS techniques. As analyzed by XRD, La1-xSrxAlO3 <...
متن کاملPreparation of Superparamagnetic of Co0.5Zn0.5Fe2O4 at Room Temperature by Co-precipitation Method and Investigation of Its Physical Properties
Magnetic nanoparticles of cobalt-zinc ferrite (Co0.5Zn0.5Fe2O4) have been synthesized in a homogeneous aqueous solution at room temperature by co-precipitation method without any template and subsequent heat treatment. Synthesis of material is confirmed using XRD from the report of single phase polycrystalline ferrite material and also determined lattice constant. Atomic absorption spectrophoto...
متن کاملCO and Soot Oxidation over Ce-Zr-Pr Oxide Catalysts
A set of ceria, ceria-zirconia (Ce 80 at.%, Zr 20 at.%), ceria-praseodymia (Ce 80 at.%, Pr 20 at.%) and ceria-zirconia-praseodymia (Ce 80 at.%, Zr 10 at.% and Pr 10 at.%) catalysts has been prepared by the solution combustion synthesis (SCS). The effects of Zr and Pr as dopants on ceria have been studied in CO and soot oxidation reactions. All the prepared catalysts have been characterized by c...
