Abstract

Abstract:

Cataluminescent characteristics of Ce _1-x Zr_xO₂(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 Zr_xO₂nanoparticles, 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 Zr_xO₂nanoparticles is associated with the rate of acetaldehyde formation.

Key words: Ce _1-x Zr_xO₂; Catalytic oxidation of ethanol; Cataluminescence; Properties of oxidation and reduction
