| Abstract: | Cataluminescent characteristics of Ce 1-x ZrxO2(0 ≤x ≤1) nanoparticles in the catalytic oxidation of ethanol was studied with focus on the effects of the chemical composition, phase structure and the reaction temperature. To understand the relationship between the cataluminescence and catalytic performance of the Ce 1-x ZrxO2nanoparticles, catalytic ethanol oxidation was also studied in a conventional catalytic reactor under conditions similar to those for the cataluminescence study. It is shown that intensity of cataluminescence over Ce 1-x ZrxO2nanoparticles is associated with the rate of acetaldehyde formation. |
