摘要：

研究了纳米Ce 1-x ZrxO2上乙醇催化氧化发光特性, 重点考察了反应温度和催化剂组成［n(Ce)/n(Zr)］对发光强度的影响. 在相近的反应条件下研究了纳米Ce 1-x ZrxO2上乙醇催化氧化反应的活性、 选择性和可能的催化发光机理. 结果表明， 催化发光强度与催化反应中生成CH3CHO的产率有很好的顺变关系.

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.

Key words: Ce 1-x ZrxO2; Catalytic oxidation of ethanol; Cataluminescence; Properties of oxidation and reduction
