Abstract
Background: The role of CeO2-doping (0.75-3 mol%) and calcination temperature on solid-solid interaction between ferric and cadmium oxides yielding cadmium ferrites was examined. Methods and Results: The results exposed that ceria improves the ferrite formation by heat-ing at 600-700ºC via the dissolution of some dopant cation in the lattice of CdO with the subsequent creation of anionic vacancies and/or formation of higher valency cadmium cation (Cd(2+δ)+). SBET of solids calcined at 500oC increased by CeO2-doping, while opposite trend for solids calcined at 600 and 700oC. The magnetic hysteresis loops of all samples showed room-temperature ferromagnetism with different hysteresis loop shapes. Conclusion: Magnetization increased by CeO2-doping that might be due to the enhancement of cadmium ferrite formation. Ethanol conversion increased by increasing CeO2-doping. Dehydrogenation product (acetaldehyde) was mainly the yield of ethanol conversion. The maximum yield of acetaldehyde (92.97%) carried out for solids doped with 3 mol% CeO2.
